Review: Funciona a la perfeccion
Review: 02/2019 UPDATE: This has been working flawlessly for over two years. I still think it's the best option for what it does, and the price is totally worth it. The Inkbird models and options are still hard to figure out. They have some new models that appear to be better-looking versions of the same functionality. The one I bought looks like it's for a garage or greenhouse but the new models are more suited to inside the house. FWIW I use these as fail-safe backups for aquarium heaters (which are notorious for failing in the ON setting). One thing I particularly like about the 308S is that it has high and low temperature alarms, so in addition to providing a high-end shutoff it will also alert you if there are other problems. I'm still a huge fan of Inkbird but they have to get their models/features straight. When I bought one of these a few months ago there was better info online but it was still incomplete and the info on desertcart is incomplete and inconsistent. But take the time to figure out which is best - they're worth it. 09/2016 ORIGINAL REVIEW: I've only had this for a few weeks but I am very impressed by the quality and operation of this device. I got the 308S with the short probe. For the price, I was expecting something pretty mediocre, but the product is solid, the programming is easy, and overall it seems safe -- which is more than I can say for many timer/thermostat products that I've bought. I have two complaints, but neither is worth a star: (1) this is made to hang on a wall/hook but a box-like format with the cables out the back would be nice for people using it on a table or desk. (2) the models and features are confusing and the manufacturer/seller would benefit greatly with a decent description/matrix of what each model and the S and T endings mean. Explain that and get the desertcart listings straightened up. This is a great product but I almost didn't buy it because I couldn't tell exactly what I was getting. It allows a narrow or wide range of operation, heating and cooling or multiple heat settings by time (different models). Has large LED readout of actual reading and set temperature, and indicates if it's sending power to the heater (or cooling if it's that model). Also has a compressor timeout feature so you can run an air conditioner on the cooling side.

## Questions & Answers

**Q: I need to heat about two gallons of water to about 100 degrees. Can I set this unit to automatically shut off at a desired temperature?**
A: You set it to maintain a temperature range of your choosing. It is designed to keep an aquarium heater from over heating and cooking your fish.

**Q: 2 heater to this unit?**
A: No. It isn't. This one can load 2 heaters. But both of them are less 1200W. https://www.amazon.com/Inkbird-Thermostat-Temperature-Thermostats-Germination/dp/B01DZ5NVBQ?ie=UTF8&me=&ref_=olp_product_details

*by N***K on 8 March 2017*

This has turned out to be a really great thermostat for a brooder I made to hatch chicken eggs. I have the heat side attached to a heat lamp and the cooling side attached to a fan in case it gets to hot. This unit also has alarms that can be set to go off if the area you are heating or cooling gets to hot or cold. There are a few other settings that are not pertinent for my use, but I could see this being used for a variety of things. There is also a setting to switch between Celsius and Fahrenheit. My only complaint is that I have had the heating relay stick a few times causing it to continue to heat even the controller shows it's not heating. I just tap the controller a few times and the relay so far has shut off. This has only happened a few times with at least a 1000 hours of use. Overall I am very satisfied with this product and would recommend it to someone who needs a small versatile thermostat.
