Interesting. I guess that's part of the risk involved with these lower cost brands with little customer service.
I'm just curious, how are the controllers dying?
I don't have a thorough knowledge of all the options out there, but I do know GVM kinda held the top spot for that price range of motorized sliders.
You may want to check out brands like Konova, CAME-TV, and YC Onion. They're going to be similar to GVM in terms of quality and customer service, though.
