Review: Broke on arrival, usable, but requesting a refund tomorrow. - I was so excited about this little tool from sram, but it's broken on arrival. I used it anyways, tool is simple to use, does the job well, however, this is made with very cheap plastic. Why not use polycarbonate for water bottles? That would have been a good and inexpensive choice considering how many water bottles being thrown away every day. Very disappointed. Need a refund. Update: I felt bad leaving a bad review and thought I should give an update. Contacted seller, they are very professional! One of the nicest response I have gotten from a 3rd party seller. Received a brand new one within days. This tool might not be of best quality, but it is usable even if its broken, and it's a must have tool. Overall: This tool is 4 stars - great design, bad quality. Seller service - 5 stars
Review: Simple Tool but Very Useful - This tool works exactly as intended. It makes setting the correct B-gap on a SRAM Eagle drivetrain much easier and more accurate than trying to eyeball it. The plastic feels sturdy enough for the job, and the fit on the cassette is good. If you’re installing or tuning a SRAM Eagle derailleur, this tool saves time and helps you get the adjustment right the first time. For such a small and inexpensive tool, it’s definitely worth having in your bike toolbox. Good value and does the job perfectly.

### ⭐ The material is a joke
*by D***D on August 25, 2024*

This stupid "tool" is a must for sram RD proper setup but the build maiteral is a real joke as so many people have experienced. I've bought one in 2022 when building a SRAM RD bike and after a couple of uses, it's left in the drawer. A few months later when it's being used again, the plastic fin first broke; then what's left got disintegerarted after still being used with struggle for a few mins. Now here in Aug 2024, I bought another one and it was already in several broken pieces inside the package upon arrival, may be due to the summer heat or being crushed en route Shame on Sram for making such a crappy item with inferior material. With so many complaints over the years, it didn't get any improvement. It's as fragile as patato chips and 100% will become even more brittle over time. If you have to buy this, please coat it with some epoxy glue which will help to hold it together better.
