It is a simple digital thermostat WITHOUT TPI (the algorithm that keeps the temperature stable and minimizes fluctuations). There are many such thermostats on the market and at lower prices. The only positive feature of this one is that you can set the sensitivity by 0.1 degrees. That is, if you want a temperature of 19 in the room, it will activate at 18.9 and deactivate at 19.1. The problem is that its thermometer does not respond quickly and to make this transition (as I measured at my home), it needs to run for 13 minutes. And when it reaches 19.1 and stops, the actual temperature in the room has gone up to 19.5 (measured with a very good digital thermometer). Whoever wants to have a stable temperature should buy a thermostat with TPI. I returned this one the next day when I realized it does not have TPI. Pay attention to the images and product descriptions. Contact the store to be sure.

In 10 months it needs to be replaced because it doesn't cut at all and makes the house a greenhouse..... plus the temperature indicated is not accurate at all

I have bought 4 for each room, it's been 6 months now and they work well... as for the temperature that they say it doesn't show correctly, it has a 'hidden' menu and you can customize it, make it cold or warm, set the temperature difference you want it to work and show from 0.5 degrees and above, and more... by holding the button pressed when it's off... for changing right-left and to go to the next function again, press the button

After 2 years of use and after the warranty expired, the thermostat broke. We made the mistake of buying the same model again but in the new version and from the first moment it doesn't make good contact. Where it works normally, the screen goes off. It has a deviation of 2-3 degrees from the actual temperature. I do not recommend it. Waste of money.

A great functioning product for 6 years and 2 battery changes. The screen lighting is good. Deviation of 0.5 degrees. Stable operation in very cold temperatures.

Deviation of 2 degrees from the normal room temperature. While it is 19.5 degrees in the hallway, the thermostat reads 17.5 degrees. The plumber does not recognize the warranty, resulting in me being charged for a new thermostat

It lasted for a year with the problems mentioned already, now it doesn't cut at all, resulting in a sauna effect at home. Turkish product, no again.

The temperature does not correspond to the actual room temperature. It would be better to spend twice the amount and get a thermostat from a reputable brand

The screen looks very good when you are straight or above the thermostat. When you are a little lower, you can't see anything

For its price, it's great. Very nice design and easy to use. It has a deviation of 0.5 degrees from the desired temperature. It goes 0.5 degrees below what we set and turns off 0.5 degrees above.

Good value for money. You put it, for example, at 20, it goes up as soon as it drops to 19.5, and it will turn off as soon as it reaches 20.5

Beautiful reliable. The only negative thing is that in both pieces I have, it doesn't secure well on the back and it can easily fall

Big flaw in the purchase.. you set it, for example, at 23 and in order to work it has to drop below 22.5 and to turn off at 23.5... it doesn't maintain a steady temperature nor can it be adjusted.

A very good, easy-to-use electronic thermostat. I am getting ready for a second purchase. Quite satisfied.
