The right VERY hard to find part at a great price.
This part saved my friend $600 dollars! That's right! He had a professional plumber stop by and gave him a price of $600 to replace two faucets with broken handles. Said couldn't get this part. I looked around to local suppliers and they couldn't find them! I did on eReplacmentparts.com!! Took me all of 8-10 minutes for each faucet and replaced the bad valves that caused these to break too. My friend is very happy and I am happy that I saved him $$$$. Thank you!

I never received my parts, I was refunded the total purchase amount. But instead i would have wished they should have resent the parts instead.
I never received the part.

The stem extension sheared off and the handle would just spin without turning the water on or off.

Removed the handle.
Removed the extension piece and replaced with the new one.
Installed the handle. Success.
This was an old Kohler faucet and many of the parts were discontinued. I got lucky and the part that I need was in stock.
