Review on 🪟 Aluminum Alloy Seatpost Tube Adapter by Bnineteenteam by Evan Larson

I was looking to replace the seat post on my wife's bike but couldn't find the right one so I ordered this spacer. Another reviewer complained that they received a plastic gasket, but mine was definitely not plastic. It's a very light metal, possibly aluminum as stated in the description. I took a photo to show how I had to install it so it wouldn't slide off. When I installed it flush at the bottom, the seat slipped through under strong pressure with all the weight. So I moved the spacer so that it hit the edge on the seatpost and then stayed in place. (By the way, Revain won't let me rotate the picture.)
