I bought these to install on my custom WASD mechanical keyboard to reduce clacking and stroke distance. I could have had WASD install them on my keyboard for $20+, or bought the o-rings from them without installation for $17+, but this seemed more economical.

With the key remover that came with the keyboard, they were very easy to install. It only took me about 30 minutes to do my full sized keyboard. The only tricky part was removing and re-installing the brackets for the larger keys.

This simple mod dramatically improved the feel of my already amazing Cherry MX Blue keys, and reduced the ridiculous amount of noise that they produce.

Not much to say - they're O-rings. They're the right size and the right material.

They work fine. They were packaged well. They arrived on time.

RELOADERS REJOICE! Are your Hornady Lock N' Load bushings allowing the dies to pop out of your press from time to time? Is it especially problematic for your powder measure? These O-Rings are the answer. Sure Hornady will send you a metal shim that supposedly corrects the "slippage" problem, but these work so much better and actually fixes the problem cheaply once and for all. They are slightly thicker than the standard Hornady O-Ring that come on the bushings and assure a tight fit with no movement. These are the rings Hornady should have used in the first place. And at this price for 100 O-Rings and two day shipping with Amazon Prime... how can you go wrong? Life is too short for "good enough" or "workarounds" Just buy them... you will not regret it.

Plain and simple these little guys worked. I used 8 of them to replace old flat ones from the carb on my motorcycle. The OEM o-rings are 3-4x as expensive and are the same thing. I would buy them again in a heartbeat, though I doubt I'll need to as i now have an extra 92 of them.

When the o-ring failed on our pool diverter valve I could not located a direct replacement as it appeared to be generic. Measured the old one with a caliper and ordered a close size. Worked wonderfully and got a whole pack of replacements for one name brand o-ring cost.

I was very pleased to find this product at a decent price and quick delivery. I needed to replace O-rings on a specialty product and feared it was going to be long and expensive process to find the right ones. This purchase turned out to be easy and inexpensive!

Let's see... Honda only sells this O-ring as part of a $15.00 + parts pack. Yamaha sells one for $1.49. This was a no-brainer. I gave a bunch to a buddy and still have plenty left over. Works as well as the OEM O-Ring I lost during my last carb rebuild. No leaks.

Use these O rings on your reloading dies in your Hornady lock n load progressive press instead of the factory ones. It keeps the dies from loosening while reloading ammunition.
