Good product for the price and really helped with project I needed them forSlight issue with inner block falling out when you release the clampsGrub screw could be better

It can be used for smaller jobs, but not for precise work.

The clamp is good value for the money paid ... does exactly what it's supposed to do ! Easy to use .... nothing complicated here ! It came well packaged also !

The worst quality ever seen.

All looks good on the paper, but as soon as you will try to use it in a real world, and you want to tighten it properly, it's holding screw shred to pieces. I had to replace the screws on both clamps for slightly bigger ones (new treading), but I haven't used them since, so not sure if they hold. Faulty design could've been sorted by adding second screw on opposite side (that will be the next step if my temporary solution fails). Clamps are ok for light use, especially if two pieces you want to clamp are different thickness, but don't expect miracles.

Great for sensitive work i.e. picture frame repairs and equally good for more sturdy jobs i.e. building frames for the garden.
