This is a good basic thumb release. It has no adjustments to the release mechanism itself. It allows you to adjust the trigger angle. That's the only adjustment possible with this. So you can't set the trigger sensivity. I like this because I've got a more sophisticated thumb trigger release which through 3 different allan keys allowing me to adjust the mechanism sensitivity of trigger and the release as well allowing me to adjust trigger placement - and it is an excellent and superior release but it also, having the complications means it's more likely to have problem and fail as it did recently and I had to send it back for repairs. That's why I bought this B3 (I've also go tthe B3 index trigger and that's pretty good I reckon). The B3 Archery Release Exit Hunter isn't as complex and so isn't as adjustable so it's not as good that way, but it is reliable and makes a good back up and it's always good to have a plan B3 if anything fails.
