I hesitated before making my choice on this model. There are cheaper goods, but which appear to be of poor bill. Even if it transmit only light, I do not want to lose the quality of the optics with a shabby housing. It presents very well, plastic that should not be expensive, but which are not cheap and we feel that the assembly is correct. the wheel is beefy, with a mechanism that I will not describe but which was worked and thoughtful. A good choice for this need (1 amp with two inputs and only need a third lot more qualitative than T. CAUTION system. There must be a cable to connect the housing inlet to the device whose wants to multiply the connections (not supplied).
