Ok

These are actually really nice clamps. They were as sturdy as the one I looked at from the local hardware store and you get four versus one for fraction of the price, so you get a lot of value for your money . Pretty easy to use.These are on the smaller side, so make sure you check to see if This is the size you will need.

Get what you pay for they are very flimsy feel like the threads will strip out but for 20 only plan on using them once or twice

Does what it says what else can I say. Good price as well.

Used one or very poor quality. not even in a box just some plastic wrappers for each of them - no instruction (ok I may agree assume this does not need instruction). No manufacturer name, no anything. Someone maybe made this in his backyard and stuck into plastic bag (yes it is these grocery store bag).

I thought they would be bigger. I can still use them but they are really small and big pieces of wood to glue together are lost on these. These clamps are for very small projects. Good quality but a pain in the butt to work with if you have big hands.

I couldn't get these to work. It doesn't really help you more than using your own hands to hold the pieces together for the right angle corner. The hold is as strong as you can turn the screw. And I just couldn't get all four corners to line up because all the pieces keep moving. I probably am not strong enough to turn the screws, which is a real pain to keep doing and adjusting. It is frustrating. So, save yourself some time and money, get something that is simpler and stronger. For me, a few quick clamps and 90 degree squares work just perfect.

I didn't expect much for what I paid for them and my expectations were correct. They feel a little light and quite honestly they feel more like cast aluminum then cast steel. I think if I were to drop one, it would break. The saying of "you get what you pay for" is correct with these clamps. If they do break, I'm only out $15. I'm sure they'll work like they are supposed to but I will probably invest in beefier corner clamps next time and not cheap out.They appear to be 90° but haven't tried them yet. Will update my review once I test them.Won't buy again. If you need a cheap set, go with these, but if you want to have sturdiness, invest more money and get bigger clamps.
