Easy to operate but the supplied software is not the best. User manual is also far from perfect.

Fairly easy to set up, and compact enough to not be in any ones way. Did the job required for a very reasonable price.

Good devices, but don't rely upon their waterproofness. Of the eight units I tested, two had battery cover o-rings that weren't full circles, and one of those was mashed into the battery compartment. The USB covers don't fight tightly, and an unexpected desktop coffee spill demonstrated that they don't seal tightly.
Still, these units do a good job of logging their data, and once you understand the software, it's actually pretty easy to use. Simple, and to the point.
Calibration-wise, I tested eight devices immersed in a circulating water-bath (submerged in double ziploc bags) with a NIST calibrated precision thermometer that read 34.5C. The eight units reported:
34.4C 34.4C 34.4C 34.6C
34.7C 34.6C 34.4C 34.4C
so out of the box calibration was pretty good.

This is a good device for the price and the latest software & instructions are easy enough to figure out, but the response time is too slow for many applications, Also, this slow response time is not even mentioned in the listed specifications, so let the buyer beware. Don't expect the actual response time to be anywhere close to the fastest sample interval, which is 10 seconds. Looking at my attached graph, I tested this device by moving it quickly from a freezer to a warm area in the house, which subjected the device to a near-instantaneous change from 0.9°F to 72.0°F. However, the device did NOT quickly respond to this change. In fact, it took almost 25 minutes before it registered within 99% of the new ambient temperature. My Warming Response Curve shows a very predicable "exponential response", and the "time constant, Tau" of this curve, which is the time it takes to reach 63% of the new temperature, is 4.8 minutes. This slow response is because the temperature sensor is encased in the waterproof plastic enclosure, which is a pretty good thermal insulator. If you aren't familiar with this type of response, realize that the same rule applies regardless of the starting and ending temperatures: it will take almost 25 minutes to reach the new temperature regardless of whether the change is from 0° to 72° or from 40° to 50° or from/to any other measurable temperatures. If a unit with faster response is needed, one should consider a device with an external probe such as this one:

Quick start guide (since they didn't include one)
1) It will work plugged in to usb port or not, but your computer will heat it up, so don't measure temperature while it's plugged in
2) You have to hit the play button and HOLD IT DOWN for four seconds to start recording
3) You have to plug it into your computer, and use the software to stop recording. Click the stop recording button at the top right bar on the GUI
4) You can't start recording again, until you zero out the data. To do so go to the parameter set menu in the software, and click on the "Save Parameter" button. You don't have to change anything, but this will zero out the data set and allow you to log new data.
That's it. For twenty bucks it works really well. The manufacturer should have spent 20 minutes on a readable quick start guide, but you can't have everything!

Wanted something inexpensive to monitor the temperatures in my home, 1 upstairs and 1 downstairs to compare the difference. So far working well.
Plugs into your computer using the USB port. First you need to install the software. The mini disc that came with mine could not be read by my computer. Not sure if that is a computer or disk issue. Regardless after about 5 minutes of searching; I found the software online on the Elitech website and downloaded it from there. [...]. I was thinking to myself, why doesn't the manufacturer just pre-install the software onto the device like a flash drive... so all you need to do is plug it in... not sure (I guess there must be more to it).
Once the software is loaded, just plug in, open the software, hit the connect button, then go to parameters.... you program the device from your computer. Then unplug it, press and hold the play button for 4 secs... and your data logging. Very easy in my opinion.
To access the data, is just as easy... just plug in, open the software, hit the connect button, then hit the upload data button. Immediately on your screen you have the data. I then download the data to excel... it exports as a .xls... (not a .xlsx) so should be compatible with almost all versions of excel. I'm using 2003... and it work just fine. (Note: in my case, it exports the data as text, so if you’re trying to build your own charts, you need to convert the data to numeric values.) To reset the device; I found the easiest way to clear the data is just go back to the parameters tab, and save your parameters again... it will clear all the data from the device.
An observation... I found that handling them effects the temp (even for a very short period of time), heats them up. Plugging them into the computer really effects the temp. While this makes it sound like the device is very sensitive, I also found it takes awhile for it to come to back down to room temp. Yea I don't get it either, (sensitive yet slow). In the computer it would heat up to about 79... then it would take almost 30 minutes to get back to 70 degrees. (I have the data to prove it; it's a data logger; lol)
I would purchase again... Haven't had them long enough to test the battery life.

I initially bought three to monitor 12VDC refrigerators while traveling. The unit used with frozen items seems to "work" but the internal clock is not working well, the sampling is discontinuous or stops (now trying to see if this is a timer issue or something else). The data are incorrect and useless. Regardless, the other two units are still working and I did purchase a replacement. Still, I'm concerned for anyone using these to monitor costly shipments of perishable goods. Perhaps if the internal clock gets more than a few seconds out of synchronization with the computer used to program / download data one should retire the unit. The price is reasonable, so I'm still going to give it four stars (with some reluctance)
UPDATE: Don't trust the battery charge indicator on the LCD screen. Remove the battery and test the voltage between deployments or every couple months. I checked the voltage on my "bad" unit and found the voltage at 2.5 V (from the 3.0V measured from a new battery). From what I've read about these batteries, they are nearly depleted at 2.6V and so I'll be replacing any battery below 2.7 volts or in use more than 6 months.

Have had the data logger for a year. The data accuracy is adequate for general usage. Software takes some time to get use to. Exported files to Xcel format and could open with my "Open Office" software with no problems. Biggest negative is that manufacture says that recording at 15 minute intervals at "normal temperatures" the battery should last a year. NO, NO, I used the recorder to record every 2 hours and the temperature never got above 90 or below 60 Fahrenheit and the battery life was NEVER longer than 10 weeks.

Worked with company but because of language differences we were unable to get the device to work. Returned it.
10 days later....
Company contacted me after posting this review and offered to send me a model RC-5+ (vice RC-5). This model does not require a device driver and works flawlessly so far. Just download the app and plug it in. I suggest if you have a Mac that you purchase the RC 5+ model. I really appreciated the spirit of the company in reacting to the review.
20 days later...
Success. Worked with the company through several versions of the driver. They are in China and I in the U.S., yet we communicated and got the job done. Highly recommend the company! I would still suggest the RC 5+ model as it does not use a driver.

I bought 2 RC-5 temperature loggers on June 24 and downloaded the required software. One does exactly what I need. It communicates with the software, accepts parameter settings, stops recording on software command, starts recording on 4-sec left-button push, clears memory on receiving new parameter settings, allows data download to Excel for external processing and display. As other reviewers noted, the internal thermistor reaches ambient temperature only after a lag of 15-25 minutes. I use that one regularly. I need two.
The second worked half way, ie, it didn't work. It displayed correct temperatures, recorded under factory default settings, and downloaded to the software. Unfortunately, it completely ignored commands from the software (eg, setting the clock to something other than 00:00 on 1/1/2012).
I returned the defective one and ordered two more (7/18). Both defective in the same way. Returned them. Ordered two more (7/26). Both defective. Returned them. Perhaps I randomly received 5 units from one bad batch. After months to let inventory clear, I ordered two more (11/18). Both defective. Returning them.
The first one still works perfectly. I still need two. Four-letter word.
Amazon should remove this product from catalog.

Looking for a good backpacking thermometer? This is it. Weighs nothing, and has a slot to secure it to a pack. The software is a bit wonky and the instructions are clearly a direct translation from Chinese, but understandable if you think about it for a minute. Seems to be pretty accurate, it was always within a degree of two different digital cooking thermometers I have that read to the nearest degree. Reads the current temp when the > button is pushed, and you can cycle thru to see the low/high temps.
The battery cover on mine was in pretty tight, but worked easily once removed--I recommend using a nickel or a quarter, NOT a screwdriver. Remember 'lefty loosey--righty tighty' or counter-clockwise to open. A firm but gentle pressure gets it moving. Be sure the little tabs are in the right place when you try to close it up. Didn't have any problems once it was open the first time. Others have had problems with seals/waterproofness, but all the seals on mine are perfect, and I don't plan on taking it swimming. I use a small piece of tape to secure the USB cover--the friction fit will hold it, but not securely.
So, not perfect, but for the price, pretty close.

Data logger is exactly as promised. Easy to use, software and documentation was provided on a mini-CD with the logger. The software (v2.0) is adequate and the export function to Excel works fine. I've used the logger with both my desktop and my laptop without issue. I've been recording the ambient temperature at my computer desk, and the results have been interesting. We don't use airconditioning, so the temps at my desk are pretty reflective out the outside temperatures. Over the last six weeks the temps have ranged from a low of 60 to a high of 87 (F) and the daily variances are plain to see in the graph the software plots. I have it set to record a sample every 10 minutes, with a data set to date of 6685 samples out of an available 32000. My intended use is to measure temperatures at our mountain cabin, and I figure that with a sample interval of 15 minutes I should be able to manage well over a six month span. Which is probably about all the battery should last anyway.

This little device is awesome! I use it to test medical refrigerators and freezers. It really comes in handy in troubleshooting the end users. I hear things like "Oh my god, my refrigerator sucks and is always out of temperature." When I hear this, after I verify the temperature is correct, I throw this baby in there and lit is sit and record the temperature for 24 to 48 hours. After that, I pick it up and download the graphs. I then export the graph into a nice professional looking report and present that report to the end user. You can't argue with data!
