Good Replacement, No Guess Work
Worked out great, easy installation. I appreciated the vendor supplying detailed dimensions of the new part so I could compare it with the worn out parts I was replacing before ordering. Replacement part looks identical to the original one. FYI this comes with 2 sets of hinges (4 pcs total), the screws supplied were also slightly longer the the original ones I was replacing which helped to give a little more purchase when screwing them into the cabinet door.

So much better than the stock ones
3 years after our kitchen cabinets were installed these hidden hinges failed. The new ones went in quickly and easily. They feel much sturdier, better quality and had no up/down play in them, compared to the stock ones.

Light duty, but they work
10lb tip out window in a Victorian bathroom is what purchased them for. The work, but are pretty light duty. Would advise anyone looking to buy them to go up a size for strength.

Sleek, Sturdy, and Simply Superb
Got my hands on these Rierdge Hidden Hinges for a countertop project I was working on, and they’ve been pretty solid. They're the 2-3/8" stainless steel type, and I grabbed a 4-pack.So, the cool part? They’re totally invisible when everything is closed up. Gives everything a neat and tidy look, which I’m all about. They open up all the way to 180 degrees, so no issues there getting to what I need.The material seems decent. It’s stainless steel and feels sturdy enough. They threw in the screws too, which is always a nice touch, and it wasn’t a hassle to install them.Size-wise, they’re not too big and not too small. Checked the dimensions before buying, and they fit just right for my project. Each hinge is supposed to carry around 10kg, and so far, no issues with the weight.You can pretty much use these for any wood or metal gig—closet doors, cabinets, you name it. I’ve only tried them on my countertop project, but I can see them working well for other stuff too.All in all, not a bad buy. They do the job, look clean, and seem like they’ll hold up. If you’re into DIY and need something that’s out of sight when your project’s all closed up, these could be worth a shot.
