Stupidly simple to use
Bought this to monitor T and humidity in my basement for suitability of wine storage. Very easy to use, super simple, data output is straight forward and versatile. Easy-peasy

Compact - Easy to Use
The mini CD that came with the product did not work. However, one call to Omega and tech support emailed me the software. Once installed, the setup was incredibility easy. I set the unit up, shipped it to my customer with instructions to install and to hit the small button on the right of unit to activate. 2 weeks later picked the unit up. Downloading the data and transferring to Excel was seamless. Highly recommend.

Works Perfect!
I purchased 2 of these about 2 months ago and they work great. I needed them to monitor temps in 2 tenant spaces.I have been using temp scribes from Grainger in the past and they are a few hundreds each. then you have to purchase chart paper and replace pencils. These are digital and can create a professional looking report to share with others if needed. For the price you can't beat them.

Can't really comment
The data logger came with a tiny CD which as everyone knows, almost no computers anywhere have a drive anymore. Went to the website to find file which was extremely difficult and once found, unable to load onto the chrome. So cant comment on items functionality cause I can not get it to work. What can be said, it thank goodness I only bought one and it was only 60 bucks!

Great product when you can find the software
I have had this about 45 days and it has preformed well. DO NOT lose the software disk that the product comes with. You will NEVER find the software on the omega site if you need to download it again
