The transmitter HSE2 868 BS from Hörmann serves me as a keychain on my car keys. The build quality is very good and in spite of the surface in a piano lacquer look no fingerprints are visible. The remote control is very easy - what is pleasant to wear, but at the same time the optical quality impression tarnishes minimal. The advantage of low weight outweighs my opinion but clear. The programming is quite easy on the hand. In my case I had the transmitter via reset switch, since our two gate drives (Hörmann SupraMatic) do not have BiSecur functionality. The procedure, however, is described quite clearly in the accompanying manual.
