I'm both a graduate degree'd engineer with a love of well designed tools and the owner of a handyman business who uses his tools daily to earn a living. With that as background ...As part of my handyman business I do a fair bit of custom carpentry that I fabricate in my home shop. I own a number of different types of corner clamps. I actually have a set of corner clamps that are identical to these clamps sold by Comfylichi, but with a different branding. The clamps and case are completely without branding, so it appears the same item is sold by various vendors here on Amazon, which is a pretty common situation. I've used that set of identical clamps for about a year on various shop projects and find them useful. They aren't my favorite corner clamp, but my favorite corner clamps cost considerably more. These are a bit more fussy to set up, but work well once in place. Note that each of the clamps also serves as a precision square, which I find pretty useful.My other set of these clamps came in a brown cardboard box, so I was pretty excited to see these came in a plastic storage case. Unfortunately the case is of such poor quality that a decent cardboard box is probably a better and more durable option. The case is made of very soft and thin plastic, with the bottom, hinges and top all molded as a single piece. This type of molded hinge is always a durability concern and mine came straight from the factory with one of the two hinges completely separated. The two latches on the front of the case are also problematic, I had to use a screwdriver to pry them open as no amount of hand force was sufficient. I've now trimmed the locking tabs down with a utility knife and they're easier to open.These are very decent corner clamps at a fair price in a subpar case. 4 stars, mainly for the good price.

Great price and quick delivery. Very sturdy and dead on 90 degrees. Once you get the hang of using them they work great. Can also use quick trigger bar clamps. These are to set your angle. You should still use bar clamps to push the wood right together. First project came out perfect. Very happy with the purchase.

I have corner clamps in my wood shop but nothing like these. The ones I have are large and kind of bulky and work on more projects. But sometimes you have a situation where the large clamps will not fit. Well, these work great in those situations. The corner clamps look well made and come in a very nice case. They are easy to use and fit in those tight spaces. The measures on the sides of the clamps are easy to read. This kit comes with everything you could need to attach these clamps to any project.

These are really nicely made and finished and work great. But having now used them a few times I don't really like this style of corner clamp. I much prefer the style where the square part and the clamp part are integrated.

Having recently been building many fun wood projects, I realized I could benefit from some good 90 degree camps for all the various square and box designs that I have been working on.I recently built a couple really nice monochord instruments. They are basically big rectangular wooden boxes that are strung with 30-50 strings. I have the parts cut to build two lager models. These corner clamps will be perfect for setting the monochord frames up for gluing. The clamps come in a nice case that fits all the pieces nicely in custom cut foam.Glad to have this nice set of corner clamps in the tool box.

Woodworking is a skill. I'm not very good at it. I'm a very strong DIYer but I'm more of the bull in the China shop. I can knock the stuff down and I can build the supports and the general stuff but when it comes to the finish work and the details I'm sloppy. I'm trying to fix that. I'm getting into building shelving and custom cabinetry for myself and I can tell you that for someone who doesn't seem to have the natural mindset for the detail work, getting some tools that make your life easier will go a very long way towards helping you ramp up your game. I'm always just holding pieces together and popping it together with my brad nailer and discovering it moved and then I don't want to take it apart to make it perfect so my work is always wonky. I'm angry that I didn't get this so much earlier in my life. Do yourself a favor start picking up the tools that will allow you to do better. It save so much time and frustration.

Like that they come with a storage box to help keep all the little pieces together. Work as expected. Tabs on box are a little stiff to open at first.
