I have a team set that I have been using for 1 year now.It works ok,I have to yell REALLY loud to activate it but then it works as it should.We even use it bike to bike and it works to about 300 ft or so ( scala says it won't !!).The batt charge seems to last FOREVER !!.I use it on standby for 1 hour a day and the charge last about 1 month or more!!.I have only charged it maybe 4-5 times in a year of use ( I don't talk on it to much,mostly stand by time ).Also I use ride everyday ( in Seattle !!) and it has proved to be 100% waterproof.One other thing,if you use it on a flip up helmet ( modular type ) you will need a longer boom mic,scala sells them for about $20.00 or so.
