For the price its great! I needed it for my full suspension bikes because the triangle is too small to fit a bottle in. I needed something that would sit up really tight to the bottom of the saddle to avoid contact with the wheel. I had tried lots of other mounts that mount to the post and none of them worked cause my tire hit them. I did end up cracking it because, I think, i bent it around a bit too much. Still great for what I needed!
I had few choices as to where to mount a water bottle on my full suspension mountain ebike. This one works great and I can easily reach it and drink while riding. Thought it was made of aluminum but I believe it's steel.
