My wife and I use them constantly.
They do an amazing job with no microphone boom in your face.
The bad:
The range on the HBC100 is not very far. You can do bike to bike if you're close but if anything is between you or you're more than 100 or so feet away they crackle and pop until you get closer. For Intercom (rider to passenger) they're great, but we don't use them for that (tried it once.) Look for the HBC200 if you want long range.
The speakers themselves are NOT waterproof. If you get water in your helmet that runs over the speaker, they will short until they dry out. It's happened a few times to us when we forget to close the top vents on the helmet in the rain. Twice they have recovered after drying out, one of them fried for good. They good news is they're not too expensive to replace the speakers.
The good:
Great battery life. They'll go for at least 14 hours constantly connected (we don't turn them off when we stop for breaks, meals etc.) Never had them on longer than that.
Simple to use. Three easy buttons. Turn them on the morning and ride all day. We don't usually touch them at all after that. They connect up easily and reliably. Same goes for bluetooth to phone/gps/music.
Smallest of all the bluetooth comms.
You can use them without installing speakers in your helmet. You do have to use the earbuds from Uclear as they have the microphone array built in. This means you could wear it pendant style with ear buds with or without a full helmet.
Anyhow, rehashing old bits. I doubt anyone could be disappointed with these.
