Product review (3 stars): Easy to Read, Great Price, But...
What I like:
* The LCD is easy to read and uncluttered
* Great price!

However, I purchased two of these for my aquariums, one fresh, one salt, and these thermometers read high: one by 2+ degrees and one by 1.5 degrees (actual temperatures were determined using an instant read digital cooking thermometer and an aquarium thermometer from a different manufacturer - both of these "reference" thermometers agree within 0.1 degrees).

Update, 9/21/17: Via Qooltek's excellent customer support I was able to trial their DC-2 digital thermometer. Compared to an instant kitchen thermometer, the DC-2 reads about 1 degree F low in saltwater. The DC-2 has an easy to read LCD, handy pop-out stand, reads in F or C, and has a clock feature.
