Bought these parts to fix the garage door opener rather than buy a new one. The parts were delivered on time with all the parts and instructions in the package. Best part...they worked great!

Perfect

Received this product very fast and it was exactly how it was described. Detailed instructions came with it. Very satisfied with the product and seller.

work just fine!

This had everything I needed to fix my Craftsman garage door opener. YouTube has some great videos for how-to instructions. Hardest part was unscrewing the opener on the first place to open it up.

I bought this to fix my garage door. I fixed it! And it works! Saved me hundreds of dollars.

With the right tools you can install in 30 minutes, very satisfied, saved a ton of money, I was able to repair my garage very fast and easy :D I will update in a few months if still working without problems.

Fits perfect

This kit saved me a LOT OF MONEY. I figured I was going to have to buy a new garage door opener, until I started watching some YouTube videos. The replacement parts are of excellent quality. If you watch the repair videos on YouTube, you can replace your gears in 10 - 15 minutes with very little effort.
