LimbSaverComfort-Tech 24009 Shaft Dampener for Shaft-Driven Power Tools, Orange, (2 Pack)

I was surprised, but they work! They don't eliminate vibration completely, but they reduce it enough that the absence of tingling in my hands and arms was significant. I suffer from nerve issues stemming from carpal and cubital tunnel as well as cervical stenosis. I can't recommend these enough!

I was on the fence, I have used them for a month, wht the heck, they work. They are kinda goofy looking, but if it keeps the shaking down, I am all in.

I was skeptical of these but needed to do something because my trimmer was killing my hands after hours of use. Installed them as closer to the guard/head as I could and the other halfway between the head and motor. The vibration reduction was great, and my hands are fine after hours of use. Do yourself a favor and buy these!

I run a Stihl FS 91. After I attached the product below the handle there was a notable decrease in vibration. I am only using one and don’t feel I will need to attach the other one.

I was skeptical at first, but before using this system my hands would tingle for an hour or so after I used my trimmer. Adding these dampeners, my hands no longer tingle and feel great.

I too, was skeptical. It actually works quite well.

I was surprised how much vibration these took out of my string trimmer. Highly recommend.

These dampers made no difference to the amplitude of vibration I experienced on my Husqvarna weed whacker.
