Went for U-Com 16 as it had good battery life, slim untit and allegedly full sena compatability, decided against integrated as you have to chuck it away when you buy new lid - my Interphone Tour system still works fine with 10+ hours of full volume music possible, so did not want to commit to a unti I would chuck away in 5 years, and extra battery life also handy.
Side by side with latest Sena it looked a lot nicer and much slimmer and battery on back is small and unobtrusive, the £100 saving over Sena also handy....
....However the voice commands just do not work, I can talk, whisper, shout, do celebrity impersonations (badly) and it will not recognize a single command, and that is in the house before bike noise and wind noise cause it any difficulties.
Needless to day it will be going back for a full refund and I guess I will just have to splash the extra for the Sena, who I suspect spent the extra £100 developing a system that works!
I would say Buy cheap, Buy twice, but at £230 (discounted from £294.50) is hardly cheap, if I had bought a Chinese special for £50 I would expect this, but not at over £200.
