Rated 3.1 out of 5 by 17 reviewers.
Rated 4 out of 5 by String little thermostat but a little hard to adjust. The thermostat works and it is really solid, no cheap parts or flimsy pieces, but it is extremely hard to regulate temperature. Since it is so small just moving the temperature setting a millimeter can result in a 5-8 degree shift in the temperature. This is entirely due to the small size and not a flaw in the product. It was, however, the only analog thermostat they had. My reason for going with this one is that the batteries on my programmable digital thermostat died and my disabled mother had an almost impossible time changing them so I wanted one that does not use batteries and for that this works fine.

Rated 5 out of 5 by replacement thermostat We had one of those 'where did we put the book, how do we adjust this, again?' thermostats that died. Replaced it with this one. Easy to self install, plus you don't need 'Thermostats For Dummies' to know how to set the temp. No problems. December 18, 2014
Rated 5 out of 5 by Very good for what it was designed for... I am the Maintenance Supervisor at a resort hotel. We needed to replace a few of our current thermostats until we got a test bed of electronic thermostats. I used this Honeywell thermostat as replacements for now and they have performed very well actually. For what they are I didn't think they were going to be around for much more than a few weeks. Surprise! Not only do they do a good job, if they are handled with care and installed correctly, they will be around for some time. I have around a half a dozen on the property at the moment and they operate just like clock work. No problems! In the end you get what you pay for, do not expect superior results from an entry grade product. However, in this case I would have to say that these did a much better job for me than the entry grade they were designed for. If the electronic thermostat test bed does not come soon, I will finish the resort with these installed instead since they have proved that well. Until I get different results, I will continue to purchase and use these. I am using these in a commercial setting and getting good results, I realize that not every situation will pan out for folks, but these seem to do very well for me. December 1, 2012
Rated 1 out of 5 by GARBAGE!!!!!!!! This thermostat is complete garbage and is not worth the money. I install one in my garage and it worked for literally a half an hour then quite. DO NOT BUY THIS CHEAP THERMOSTAT!!!!!! Spend a little more and get one that is reliable. October 19, 2010
Rated 3 out of 5 by Good for the Price Solid construction and easy to install. However, it is hard to regulate temp as the thermometer inside this thermostat is not very precise. Good for the money but a digital one for a few $ more would be my next purchase September 23, 2014
