Been using Chatterboxes for 15 years. Work very well on the VOX system for small group, 5 or 6 sleds. Our group has increased to 9 or 10 & now sometimes get static, push to talk button mounted on handle bar solved those problems. Guys in middle use PTT, lead guy & sweeper using VOX worked best for us. Very nice to have when front guy sees trouble ahead. Nice to know when sleds or a bad corner are coming and for guys in back to yell for a downed sled or something. Batteries last all day when charged, replace about every 2-3 years. I drain mine & recharge for a couple of cycles a week before our first trip. Helmet Clips - yep, by a couple or make one from aluminum or something, they break easy when cold. Did see some guy on ebay selling aluminum ones, but haven't seen it lately.
