Communicators?

I need to pick one up pretty soon here- still haven't invested in one. What type do you guys use? What do you like/dislike about them?  Anything to keep in mind when shopping for one?

I'm looking at a Sena 20S - like one of these from Amazon..

Thoughts?

Total Sena devotee here!! Currently running the 20s myself, incredible piece of work! Been using Sena's since their initial introduction many moons and a few versions ago, great customer support and there technology is andxwas honed in the medical field so you know that reliability is a priority for them! I still have a lot to learn as far as being a user goes, this 20s does SO many things!!

I also use the 20s, really like it, phone calls are crystal clear, other person doesn't even know u r on a bike at 75mph, music is great too.
If your helmet has a lot of noise, it might trigger off the sena voice comand a lot, my old helmet did it, new never does.

Another vote for SENA 20s. Purchased last season for two up communications with my Wife. I use when soloing also. Highly recommend.

Sena 20S here also, not perfect, but closest of any that I have tried. I have not quite figured out how to get it to comunicate with multiple riders at once, could be a Bluetooth pairing order thing I just haven't  figured out yet. Can also be a little tricky to get the volumes balanced between intercom, phone, and music.
