  • Perfect Square. Easy to Use!
Style: 4PCS 5.5'' + 4PCS 3''+BOX
Makes 90 degree boxes a heck of a lot easier! Good sturdy build and thickness and great value add. Easily a must if you plan on building anything.

  • Quality Set
Style: 4PCS 5.5'' + 4PCS 3''+BOX
This appears to be a quality tool set. I have yet to check squareness, but the whole kit comes in a sturdy, die cut foam storage box. Will be a plus to help me build great shadow boxes, drawers and art frames. The two sizes are a plus for different size projects.

  • Useful
Style: 4PCS 5.5'' + 4PCS 3''+BOX
Pros: Container helps keep components together and organized, easy to find all of the parts when using, two different sizes help with different sized projects, threaded components run easily for fast set-up, clamps hold well into angles, lots of clamp holes to adjust for differences in projects, the chrome finish on the clamps appears to be excellent. Cons: Components can be difficult to removed for the container because of tight tolerances in the retention foam, the read surface finish seems soft during initial use and is expected to wear considerably over time, I found it useful to use four clamps per angle so that the project remains aligned with the angle this means there are only enough clamps to use two angles at a time, I would consider separately purchasing additional clamps even though there isn't enough room to store them in the same container. Value: pretty good, useful for the intended purpose, I used product on an actual project and had good results. ... show more

Very good quality and nice case to keep them inside. Well worth it.

  • Great flexibility
Style: 4PCS 5.5'' + 4PCS 3''+BOX
I've used these on a couple projects now. They work well for both calming to glue parts, or to hold for screwing them together. All the need is a corner, even if the larger shape is irregular. The storage box is a nice bonus to keep everything together, and out of the way when not in use.

  • Good product, great value.
Style: 4PCS 5.5'' + 4PCS 3''+BOX
Very well made. You get 4 large and 4 small corner clamps, so you can put everything together at the same time. Unbeatable at this price. No instructions, but it's pretty much intuitive -- else, go to YouTube for a demo. This will greatly simplify a lot of projects: cabinets, picture frames, window screens, on and on. ... show more

  • Good clamps
Style: 4PCS 5.5'' + 4PCS 3''+BOX
These clamps work very well for any 90° carpentry.

  • Poor quality control
Style: 4PCS 5.5'' + 4PCS 3''+BOX
One of the knobs was missing the threaded insert making it useless. I would install my own nut but so far have been unable to find a nut with whatever thread size they used. The product seems otherwise well made and is packed in a sturdy container, and all the corner clamps checked at perfect 90 degrees. Would have given another star but for the missing knob. ... show more
