5 of 5 Top notch service July 12, 2023
Reviewer: Jessie from Rochester, MN United States  
Part was received in a day in a half.  Amazing service for a ten dollar part.  Fixed and now works smoothly.
Saved on a $150 service call.  Whenever my garage door opener finally goes I know where I will be purchasing from.  Star Door Parts!

5 of 5 Works as expected May 3, 2020
Reviewer: hablex from East Coast, USA  
The gear came on time in new condition, and they also threw in free gear grease as part of a promotion. (Gear grease is mandatory with these plastic gears). I installed the gear in my garage door and now it's working perfectly just like it used to.

5 of 5 July 28, 2018
Reviewer: David Wagner from Coeur D Alene, ID United States  
The main gear in my craftsman garage door opener stripped out. Being the opener is 21 years old I thought I would never find the part I needed. I found Star Door Parts on line and almost immediately found the part I needed. I ordered it on a Saturday and although it said on the website they would process my order the next business day, they sent an acknowledgment of my order right away. Then on Sunday I get an email saying the order has been shipped. It was at my house three days later with the required grease for proper assembly and free shipping the whole thing cost me $6.00. I am very pleased with Star Door Parts. And wouldn’t hesitate to order from them again.

5 of 5 Parts February 25, 2018
Reviewer: Lance Clifford from Portland, OR United States  
They had the correct part for my 40 year old garage door opener.  Instead of having several hundred dollar replacement I was able to replace the stripped gear for under ten dollars and a hours work.
