In general - useless garbage, due to low power. Just money down the drain. Different pros: The manufacturer has modified the heater 1. The display has a beautiful dimming screen, it folds back so that the blue light is muted at night and doesn't get in the way 2. Clicks. They became very quiet. Even at night, in complete silence, they do not interfere and do not wake up. Has some cons: 1. The 1000W model is almost useless, don't take it! My room with plastic windows of about 10 sq. M. cannot heat. The door to the room is constantly closed, but if the temperature outside the window drops closer to +5 degrees, then the heater can no longer keep a comfortable temperature in the room, even when working around the clock at full power. Take immediately models for 2022 watts. Maybe they'll be more efficient. I also have to add a heat gun. 2. There is a frame on the back for wall mounting. So, keep in mind that the metal there is sharp - like a knife blade, do not try to move the heater holding on to this frame (for example, if the heater is hot), in 90% of cases you will cut yourself.
