After reviewing the Sena models they appear to be a step ahead of the game in terms of technology, likability and apps to assist with setup.
The collect brand seems to have fallen behind while still charging more and after reading the reviews, their 2 mile claim is not accurate and the range is likely similar to the 1.2 miles that Sena claims. I am hoping the less expensive Sena 20s will be just what we are looking for!
