Have the Thebes for some time now in operation and it is very reliable. Why I give only 3 points for the following reason. The display is not illuminated in blue, as on the HP at the image, but gray with black lettering that is not easy to read for me. The Temperaturstellrad right is relatively smooth and is adjustable heavy, which is very annoying for me because there is no own hotkeys to quickly switch from day to night or setback as it had my old one. The menu is also somewhat cumbersome and getting used to. Who sets the Ramses 1x and then leave them alone, for it is certainly advisable and recommended ..... the quality is just the reasonable price
