you have to be careful when you use it as it WILL scratch your limbs over time, since its pure plastic it doesent have rubber or anything to protect the limbs, also the fit is quite tight on my SAS RAGE, and they only fit fully on the very end of the limbs next to the pulleys, im still trying to figure out how to add something to the clamp to keep it from scratching my limbs but havent figure it out yet, they do a good job of keeping the bow standing if you have a long stabilizer,(at least 8-9 inches on most bows) for the price and with some work to protect the limbs this purchase might be worth it but if you can find one with rubber at the clamping point for a similar price buy that oneMy kids like using these. I am not a fan mostly because I don't like the idea of tension on the bow or putting my pulley/string on the ground. I bought this for my son. It needs COLOR to see it when you lose it out of your pocket. It needs a better way to carry it when its not attached to the bow. Seems like I have to keep replacing it after every 3D shoot cause the kids keep losing them. And no one ever turns them in to lost and found.my bow limbs are wider than what these will go on but they look niceWorks okay but had to make an adjustment. The gap is too wide for the limb on my Diamond Infinite Edge, so it was way too loose. Filled in some of the space with tubing and silicone. Now it's a fit.Doesn't stand my bow securely at all! The spring is very weak, and none of the pre-cut notches fit my PSE Vengeance compound bow quite right. I would try putting some foam tape in the jaws so they would fit better, but even then the spring is so weak it would easily come open if something even lightly tapped my bow while it was sitting. When I clamp this on my bow, and rest it on the floor (on this clamp, and my 10" stabilizer), it it is so unstable I don't trust it at all. Also, when you pick the bow up, this stand flops around loosely.I do not recommend you trust your $300-$1000 bow to this clamp/stand. I'm planning to return it, if I can.We bought 3 of these to use during our state tournament. They were great to quickly snap on our genesis bows during all events (3-d, field, modified 600, etc). They were able to be snapped on one handed and came off hair as easy.When we first got them we were a bit confused about how to use them without putting the cams into the group, but quickly figured it out.It does the job, I cant expect more. I wouldn't pay more for it even if it was perfect. I like the spring and the plastic. It seems well made and will last a long timeI didn't personally buy these nor do i use them my husband did and does. He hasnt complained so i assume as expected.
