Review on 📱✨ Topeak F55 Fixer: Black Phone Pack & Tool Bag Holder with Moonshine 3H/HID Battery Mount by Carta Gutierrez

I bought this to mount the Topeak multitool on my seat post to save space in the bad one that attaches to my saddle. The post that the tool is attached to works well with a decent clamp. However, the strap around the seat post is made of plastic that is too hard. When I tried to loosen the strap to attach it to the seatpost, about 1 inch of the strap came loose at the end. I was willing to accept this as there was still enough length left to bypass the seatpost. I attached the strap and started tightening it until I felt it wouldn't slip over the seatpost. As I made the last few turns, the belt broke again. This time right on the edge of the screw. It cannot be used now. I replace the strap with 2 zippers.
