I've got one and I like it... reminds me of a Motorola HT. Solid and well-built, long-lasting battery - still missing a few "ham-centric" features (DTMF for one), but the developers have been issuing periodic firmware updates that add features and performance (and DTMF is on the list). The chinese company even has a Facebook page where they interact with users and provide support. While you can certainly find complaints from other users, mine has been pretty stable, so I suspect that the programming complexity, typical for a DMR-capable rig, has a lot to do with this.
