Multi Angle Degree Corner Clamps, Adjustable 30-90 Degrees Sawing Mitre Right Angles Measuring Cutting Tool for Woodworking Photo Frame (red)

This is interesting, I really like the variable angle design.It is simple yet clever.Easy to use, and clamp your workpieces in.The main concern I have here is the materials it is made from.I have other wood working plastic clamp tools that are fine, and made from a more dense higher quality plastic, this is not quite up to that same standard.The plastic you can tell is a little cheaper.It is overall decent, but I do have some quality questions.For instance, it clamps tightly and accurately, however I am concerned with how much clamping force you're putting on the mechanism, that it may not last super long.When I first got this and was articulating the sliding angle adjustment on it, a screw just fell out of the bottom. It had red plastic on the threads, and looks like it was over tightened and stripped out some of the plastic in the hole.This seems to do the job fine, especially for smaller and more light weight projects. If this breaks within a few projects, I'll probably come back and lower the star rating. For now, it is merely a suspicion that it may have some problems after repeated use - but so far it is a hunch and unfounded.This same tool in aluminum or a higher grade plastic would be great, as it is, still recommended because it seems to work well, even if I am mostly going to be using the 90 degree angle, it is nice to have options.

This "clamp" did not work for me. It is made of plastic and does not hold the pieces of wood (1x2 pine) securely in place in order to screw together or to glue. My one project called for a triangle shape and this "clamp" did not work. My other project called for a rectangle and this "clamp" would not even work for 90 degree angle.

I have a metal corner clamp, but it was pretty pricey. This is a nice alternative to the expense versions. It's a thinish plastic, but once it's clamped in place, it holds well. If you wanted to glue picture frames, this is an affordable way to buy 4 and get the whole thing set in a day

I've been trying to get these to work for me but honestly, just not that great. Cheap plastic and not truly accurate. It's good enough for getting corners to hold together while tapping in a couple of brad nails for shop furniture or things like bird houses but nothing too thick or too heavy. Make sure you have your corners dead accurate because the jig just isn't,

These are okay as a lightweight positioning aid for small material. The material clamps don't really "clamp" they just keep the pieces pointed the direction you want. They lock in place but don't apply any significant pressure. The locking cam is all plastic and requires enough force to lock that there is a fear of breaking the locking tab off. Having said that, I've locked and unlocked them several times and they seem to be able to stand the force. The angle measurement seems spot on. I checked it with a good protractor. The locking pins, angle set screw, and the main pivot are all metal and are well made. The material clamps can take up to 3.5 inch width. If you need to handle larger stock or if you need significant clamping pressure, this is probably not the corner clamp you need. If you primarily use smaller stock and just want a jig to hold things in the right orientation long enough to do what you need to do, this may work for you.

The media could not be loaded.  This seems to be a pretty cheap plastic. I can't get lock tabs to lock the slides into place. It does expand by releasing the knob.i guess it's OK for some small home projects but not for big projects that need good tools

Somewhere in my workshop, I have a cast-iron version of this item, and the reason I say "somewhere" is because it's so heavy, it's a real hassle to use. This lightweight version will never be as much of a work-horse, but being lightweight, it's so much easier to manipulate as you clamp everything together. Boy do I have a whole lot of mitered corners that probably would've been just a little bit neater if I'd had this before sooner, but better now than never.

Very easy to use. Just slide the clamp and lift the lever. It's also easy to change the angle by just loosening a screw and expanding the edges. The angle gauge is marked but it is slightly obscured by the tool and the numbers are hard to read. This is a simple, hard plastic. No reinforcements cast into it. Just be careful with it.
