I purchased two of these. My needs are to talk with my kid who is new to riding. I feel based on the price point the 3s is an excellent product. The range is not great. You have to be within 100 yards. You lose contact around turns even when closer than 100 yards. My phone works well thru the 3s. I am happy with the system. Limited range and functions but it is an entry level unit and does what I need. I will purchase a higher end model when distance is needed.
I wear a Daytona skull helmet and it fits great with that. Sound quality for phone calls is excellent. Audio for audio files is just okay. Works great for me as i like to ride distance and this keeps me rolling when a phone call is necessary.
Exceeded my exceptions. The range is better than I thought it would be, which is a pleasant surprise. The sound quality is very good and loud enough to hear over the rumbling of my Harley. When I speak to people on the phone that can't believe I'm on my bike. It really eliminates the back ground noise. Would highly recommend this product.
This is a well thought out product and well worth the $135 (includes chip price). The sound quality is much better than I anticipated and the video is also quite good. The form factor is so small, you don't even know it is there. The audio voice prompt (camera on/off) is a nice feature. It does what it is supposed to do without the complexity of other cameras in this space.
