The two stars I was only in the possibilities and the concept of Harmony's. You can really control a lot and works very well. But the quality of this FB is really unreasonable. The IR signal is very weak that precisely targets and no Hinternisse may stand in your way. After half a year the label the keys replaces. There is no evidence from the FB on batteries. All these points ägern me so because I'm actually better much better accustomed to the 555. It is inconceivable to me why good equipment will not be developed and replaced by this "garbage".
