Product review (1 stars): Data Loser not Data Logger
I had a new refrigerator that would fluctuate in temperature radically. I've used USB data loggers at work before for various reasons and thought buying one and installing it in the fridge would provide a data record that I could show to the warranty repair company to help diagnose the on-going problem. I purchased the EXTECH RHT10 expecting the same reliable results as the EasyLog USB data logger I use at work. When I tried loading the provided software, It would not load. Finally after the 3rd time of trying, it finally loaded. I put the data logger in the USB port and my PC indicated that it was not connected. Then logger then seemed to connect and disconnect every 5 seconds. After a reboot and another try, I was finally able to connect and set up the logger. After setting it up, I disconnected it, started it (watched the LED blink every time it took a reading) and set it in the fridge. After a week, I plugged it into my PC only to get a message that the logger had zero data! It then started it's connect/disconnect sequence again.
It's bad enough that this product didn't work, It's worse that it lost vital data.
Bottom line. Buy a better product and test it several times before recording vital data.
