Order these for my son and I when we go dirt biking and four wheeling took them down to Hatfield McCoy in West Virginia. We had two side by sides between us and we're still able to talk clearly to each other I also use it on my street bike for directions works great. I don't know maybe the other ones that are more expensive are worth it but these seem to work fine, especially considering the price.
Got two, feels and looks well made and came with plenty of installation parts. The clip version might not fit some helmets, but, double tape install comes with it, Mike looks good. Let's see in 6 months how it holds.
