OEM clamp on my Rad Mini broke, so I purchased this item. Works great and is better the the stock clamp that came on my Rad Mini e-bike. Build quality is excellent compared to others I've seen and used.

Didn't fit my bike so I'm leaving 3 stars only because the product itself feels good quality and is a nice style. Just doesn't fit my bike right and I ordered the size I needed.

I like this quick-release clamp, my bike, which is a Co-op DRT 1.1, came with a bolt-style seat-post clamp, which while being the most secure (arguably), is the slowest for dropping your seat and the least ideal for mountain biking (MTBing). It's pretty secure, although I have had it come loose a few times while riding. It wasn't like the seat just dropped, the saddle just shifted to the side. I'm pretty sure it's caused by all the vibration from riding (I have a hardtail, so a full suspension will have less of this issue, while a rigid will have more).
No biggie, just check the tightness of the clamp every month if you do normal riding, and maybe more if you do more gnarly MTB riding. I just never check it until it loosens too much, so that's on me. I never remember, so my solution was to take the clamp off the bike, unthread the bolt from the lever, apply a drop of blue 242 Loctite, screw it back together, and install as usual. It's been fine so far, and the threadlocker will prevent it form coming loose again (at least for a long time), but you can still disasemble it.
I've had this clamp for just over 15 months now, and it's not showing an major...
