Vibration Dampening Inserts Made in the USA For Metal Golf Shafts Reduces Shock & Vibration on Impact For Sting Free Golfing Ideal For Golfers with Arthritis, tendonitis, & Joint Pain 9 Pack

Club builder, used these. Snapped 4 shafts, all in the same spot. Shaft manufacturer, and I, agree. Causes oxidization in the shaft that can cause breakage.

I work in a pro shop, and after using these myself and being very impressed, I have recommended them to at least a dozen or so customers. They in turn recommended them to their friends, so all in all I’ve probably installed about two dozen sets of these. The key to installing them is use common sense. Do not use the installer tool at the very beginning. Hand feed it near the shaft, grasping the foam sections and pushing down with each one. When you get to the last foam section, at that point you use the installer tool . From there on they go down with no issue. These have been a game changer for many of my customers, as well as myself

I had switched from my longtime modus 120 over to graphite solely for the vibration reduction fighting a nagging wrist injury. The graphite performed as expected but unfortunately didn’t work with my swing and had to swap back to the modus so I ordered these thinking it was worth a shot.I disagree with some of the other reviews that say it’s nothing like graphite. The feel and vibration reduction is very similar if not identical to my previous graphite shafts. I installed a single shaftease in my 8 iron first to see if it was worth the hassle and hit it side by side with my 7 iron without the shaftease. The difference was very noticeable to me. Pure shots felt soft as butter and off center hits were much less penile to the hands and elbows. Really happy with the product.

These are terrible. Tried installing these in .355 DG and the plastic straw down the keeps buckling and the end keeps gapping and the tool keeps sliding into the straw instead of pushing the dampener down like it’s supposed to. Not sure if they are meant for .370 shafts but I saw no mention of that. I have use sensicore and prosoft before and they both insert how their meant to. Harder to find sensicore now but I will be ordering prosoft instead of these.

Can only install with new grips. Some collapsed when trying to insert. Would be better with a firmer center straw.
