The product was shipped to Colombia. It arrived in perfect conditions and very quick. Thanks!!
These look like a great idea at first, but the plastic part can come out and beneath it, the screw can't be tightened or loosened with a regular screw driver, like you can see in the picture. So, if you don't have a special type of screw driver, and the plastic thing is not able to tight or loose the screw (which is what happened to me with one of these), well, you are basically screwed. You will have to use some pliers. So i don't recommend these type of clamps over the traditional ones.
