Well that's not Gates but Gate's representative which you dealt with. That doesn't mean that "Gates" the housing manufacturer failed you. I think there's a magna differentia .
Back in 2007 when I was using a Light and Motion A1 set up I wanted a larger top mount monitor than the 2.5” available via L&M. I contacted Gates UK distributor (Cameras under water) but they did not seem interested in making the gates monitor work with my L&M housing so after a few emails and phone calls I gave up and contacted Amphibico who were happy to give me wiring instructions to make their 3.5” monitor work with my set up, should I wish to buy one. About 6 months after that Amphibico built a custom housing for me at a very reasonable price and I have used them for the last 4 years. I am very sad at their demise.
