Review on 🚲 FOMTOR Adjustable Bicycle Seat Post 25.4/27.2/28.6/30.9 x 350mm - Alumium Seatpost for Mountain, Road, and BMX Bikes by Brent Peterson

Firstly, it didn't come out as originally promised; lasted four days when Revain Prime had a box office rating of two. When it arrived the seat post clamp bolt was completely immobile. I tried to lubricate it on the nut with pliers, holding it and putting a lot of pressure on the hex wrench. Nothing worked. I've built road bikes from scratch and have never come across a bolt frozen like this. I'm not sure if it's glued in there, cross-threaded, or if they used a power wrench to tighten it there. Considering there are currently two other reviews saying the same thing out of 28, it sounds like 10%+ is DOA, so beware the buyer. going back.
