I don't often have a use for corner clamps, so I leaned toward the cheaper end of the spectrum. The best word I can use to describe these clamps is "dainty". They are small with very cheap hardware including super thin tightening handles. I was able to use them to clamp up some fairly large picture frames though. If you only need to use them on a rare occasion, they will get the job done. If you used them more frequently, spend a few extra bucks and buy something more substantial.

Good value for the money but lets be honest, these are low quality.They do however get the job done they just take a lot of fiddling to use.

There awesome they work great

The GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools are great at making pieces of stuff touch at right angles. Not really big stuff, mind you, but smaller stuff. Since I only needed small stuff to go at right angles, and they told the truth about the size of these, this worked fabulously for my purposes.In the past, I've consistently had problems connecting things at a true right angle, sometimes 87*, sometimes 92*, but never a perfect 90*. No more! Thanks to these lil guys, every relatively small thing I want to attach to another relatively small thing at a right angle- bingo! They don't even have to be the same smallish size, just kinda close. Just shove 'em in, clamp 'em down, soak 'em in some glue, let 'em sit overnight and BAM- they're affixed at right angles! Just like that! No muss, no fuss. I'm not sure what muss means. If it's the same thing as mess I've been having issues with that due to my tendency to "soak 'em in glue", but I just get so excited about my GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools I can barely contain myself, if you know what I mean. You could probably use screws or nails or something and get the same results without all of the muss/mess, but I'm just an old school glue guy like that. My kids keep telling me I'm tacky I like glue so much! *rimshot!*Now, I have so many things in my life at right angles it's craaaazy! And cray cray! Do the kids still say that these days? I think they do. If they don't, feel free to substitute more timely slang above. I've even taken to framing out our towels, pillows and pets to perfect 90* angles with the ol' GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools!Please don't take my references above about the items that can be clamped being small as in any way a criticism of the GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools. As I said, they are true to the size stated in the listing. I've just gotten a hankering to start attaching larger things at perfect 90* angles, and haven't found a product that works nearly as well as the GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools for that application.My wife says I've become a 90aholic, but what does she know? I can stop any time I want to. Fine, bring on the 45*s and the 30*s. I don't have a problem. If I did, I'd just put it in the corner (see what I did there?).So, about right now you're probably wondering "Gee Neil, the GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools sound like they've been a truly life changing product for you, but what's this four for the price of one of which you speak?". Well, lemme let you in on a little secret, friend. If you poke around much on Amazon for this type of tool, as I often do, you'll find suspiciously similar one and two packs for the same price as this four pack and those don't even come with the utterly worthless and pointless case (a word I use extremely lightly). I have a funny feeling all of these identical-looking items, many of which have the same stock photos in their postings, all come from the same factory in a certain little country and are imported and sold by different folks at different prices. My point being is that this is the greatest amount of GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools you can get for the least amount of money. Why get just one or two when you can get four for the same cost, along with that garbage case that can only fit like two of the four GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools?I really was going to only buy a two pack when I found this posting, and, honestly, having four really does make the job a lot easier and faster. Also, the case really is pointless- it's too small to fit the tools unless you're a Jenga master or something, but like most people, I have a bin of clamps, so I really didn't care. Also, these things are stupid expensive at the store. Before these, they always fell into that "seems cool, but not spending that kind of money on something I probably won't use all that much cool". These are cool enough to spend this greatly reduced amount on.Now that we've gotten to know each other so much better, and I consider you a friend, as I hope you do me, I say "friend, go right on and buy this handy dandy (I don't know what dandy means either. I think it's an old-timey British word that means effeminate and has nothing to do with clamps) four pack of GoLucky7 Right Angle Clamp, 90 Degrees Corner Clamp, Picture Frame Holder, Glass Holder, DIY Woodworking Hand Tools! You won't regret it, but your previously obtuse/obese pets might!"

Works great! Also LOVE the storage bag it comes with!

A little flimsy but to make a few frames it is great.

Making frames with 1X1.25 wood and Elmers glue. Out 8 frames, only 1 joint was off slightly.

The clamps were delivered promptly. And they were square once I had them properly seated in the clamps. The clamps are easy to use and will serve well as my second set.
