It's a binder clamp, what can you say? It's well made, I've had several and none have fatigued in six or seven years. The lip on the top is a nice touch. They look beefy but are reasonably light. Be sure to order the correct diameter, not your seatpost diameter but the seat tube, don't ask why I brought that up. Comes in black and silver, I have one of each, they both look great. I use them on two different carbon Cervelo frames.
I was having an issue with my seat dropping down slowly and occasionally even twisting during my ride. I would have to stop intermittently to readjust it during the ride. I swapped out the factory quick release for this beefier Lip-Lock and the seat now holds firmly in position. As a bonus, I no longer have to worry about someone flipping the lever and walking off with my saddle. I highly recommend this over the stock seat clamp. You will not be disappointed
This is just one of those things that you lump in to the cost of buying a new bike, along with a Thomson post and and whatever saddle you prefer to ride. Even top end bikes usually come with some glorified pipe clamp with a junk bolt threaded directly into low quality aluminum. Strippedloose seat binder tops the list of unlikely equipment failures that I hear from DNF'd racers all the time. Get your saddle where you want it and then KEEP IT THERE. The steel nut-insert in this makes it about infinity percent better than most stock binders and the bolt is a nice big hex size that you will never strip. It's like one gram heavier... do it.
