i am a very still install and was doing a cheap deal for my customer who wanted a cheap intercom system, so i f up again and buy cheap item from Amazon again. after buy 3 difference, L Z bracket i still had to use a metal screw to fit the magnet lock on. the job turn out to cost more and i lost an importance customer and friend. i manage to fit the system on and connected 3 open point to 2 building. but the key fob is not working so not sure how i could charge for my job, before i use amazon to buy cheap items that the china dump to us with faulty designs.please you need to stop this as we can not keep buying cheap item and do not have the time to return. not only for that reason, it cost me 1 week of my time and all my hard work wasted for your cheap item that do not work. i would rob that uk CEO some day soon just to let him know the feeling.
