I wouldn't put the Lectro LT/LMB into the same category as the Azden and Wireless Go. It's a pro system that will outperform every other system in the prosumer category by a huge margin. I have a couple sets of the LTs/LRs and they perform nearly as well as SRCs and 411s/smqvs. They're also wideband so cover three blocks.19ms of latency isn't a benefit at all for the Deity Connect. It makes syncing with analog sources like a boom difficult. That should be in a con category.
There are actually quite a few cheap GoPro frame mounts out there that offer many of the features that this has. I have a metal case that allows you to use the bigger external GoPro battery, 1/4 mounts for mics or accessories and a filter thread. It does vignette a little on the widest setting, so I wonder if this one clears completely. The expanded memory is nice, though. That's a first.
