This style of clamp is iconic, and with good reason. They have a very strong bite, but if you are going for clamps that look like this, that is probably exactly what you want. The connecting chain is lighter than I expected, but not bad. The way they bite, they probably shouldn't ever be puled off, but that would require a lot of force. Probably not a good choice for your first clamp, but these are definitely high quality, and I don't regret the purchase at all.
