I have not personally owned one but I have only heard good things about them. The local DMR group has been using their c-Bridge without issue for a while now.
I own a BCR-40U repeater (GMRS) and a BCH-220 HT. Both are very well built. They are designed in America and built to specs by various manufacturers. The ones used in the repeaters are built by the same company that built the Maxon gear.
I was looking at their website last night, and I see they have a couple mobile units with pretty standard band splits, VHF 136-174, and UHF 450-512, so I'm assuming those are part 90?
