I bought this type of head to modernize inexpensively my setup and manage my radiator time slot. The material makes the job, but the build quality is poor. the very tight fit of the hull and the design of buttons that when I press a button, the deformation of the plastic that it supports the same time on the 2nd button. And conversely, the positioning of the LCD game that he may lose his contacts and the LCD turn off. Add to this that I have 25% of my head that I have to change several times each winter batteries. And it does it happens when the batteries are dead? I give you a thousand, the radiator is blocked on open or closed. When you return from WE winter and you notice he does 26 °, you say that the weak economies of the system are in smoke once. I would also mention that the "open window" function spasmodically walk In short, I may be wiped casts being one of the first buyers, but in any case, I can not advise on the purchase.
