Rating : - It does the job but it's not reliable.
I bought 3 sets for me and my friends for our 10 day motorcycle trip. I made the installations on a Nolan flipface, Arai flipface and a Shoei motocross fullface helmet. The success of installation depends on your abilities. I decided not to do as they said in the user manual and ended up with a much cleaner and less exposed installation. The extra fullface microphone kit we purchased was not necessary. The reason they sell this item is the limited mouth clearance on some helmets. If you have more than an inch between your mouth and the helmet wall, you don't have to buy the full face kit. The one in the box will work. If you have a flipface helmet, you cannot use the fullface kit anyway. You will have to live with a microphone touching your lips all the time. But you get used to it. Do not remove the sponge wind protector. One of the guys lost his and it became hard to understand what he was saying.

I think the unit provides basic communication. There were many times we were glad to have it. We warned each other in the traffic, laughed about things, let others know about our needs. Being able to communicate on a bike is great. But if you will depend on this ability, you may consider something better. There are inconsistent failures with the units. One of us could not use the ptt handlebar switch because the receptor port on the unit was not working. This was a problem right out of the box. We did not have time for a replacement. The range was about half a mile or one mile at best. We could only talk when we saw each other. The auxilary input was great. I could listen to stereo music and gps instructions. But i could not speak when I did that. Sometimes one person in the group cannot talk or listen. But this is really random. Next day it's fine. The unit also acts unpredictable when the batteries are low. One of the guys was complaining about a constant hissing on his left speaker. I lost one of my speakers after 10 days.

The best thing about this item is its pricetag. It will add to your riding experience but will not solve your radio needs forever. We had the option to get these or not get anything at all. There is nothing that compares in price. It payed for itself but now I will be looking into something else.
