I do like my Sena 20s's, I did have one stop working while under warranty and they did replace the unit eventually but it certainly was an exercise in aggregation and patience. I went back and forth with them via email and on the phone, the whole process took about 5 weeks to get another unit in hand under warranty. I can't speak for its durability in wet conditions as I have only been caught a couple of times in very light rain with them and my madstad kept them from getting wet at all.
