Sent an email asking what sensor to use to replace my inop one (lasted less than a year). Sent a form email saying they would get back to me. Never did. Don't bother calling, their recording told me on several tries that I was something like 80th in the phone queue and I would be waiting 300 minutes. These folks either sell so much foreign garbage that their customer service can't keep up with the complaints, OR they just don't give a damn!! If you need something that is relatively cheap and won't last long, and you are willing to trash it when it quits and go out and buy another, these are the people for you. The Chinese DO NOT manufacture quality goods, just cheap JUNK. And Cheney, like so many other "American" companies have jumped on the cheap vs quality bandwagon. What do you think Trump is trying to do with these tariffs? Maybe restore some semblance of QUALITY to the goods we are forced to buy?? At first I thought Trump might be a buffoon myself, but now I am starting to think differently.
