I think the only bad reviews I've heard of was for the early versions of the Innovate LC-1 widebands, multiple failures. Understand the one they're selling today had been fixed and the issues no longer exist. You have to be careful when buying an used LC-1 due to this issue. The LM-1, not sure if i've heard of issues on that one from Innovate. I may have them backwards, whichever one was the least expensive was the one they had the issues with.
