TamBee 90 Degree Cabinet Door Hinges - Concealed, Non-Mortise, Zinc Plated, Alloy Steel, 4-Pack

Who knew hinges were so complicated. Bought four different ones that didn’t work for my installation before these. As others have said nearly impossible to figure out how to open and close them. I even broke one trying to pry it with a screw driver BUT that showed me how it worked so I was able to install and Voila! It worked perfectly. Project complete. Google it there are videos showing how to open and close them. Maybe manufacturer could put a video address showing how it works and some directions with the hinges so others would not have the problems of trying to figure them out.

Easy to install, and the quality seems really good. There's a little play in the hinge, but I'll bet you'd find that in most of the hinges of this sort. It's a complicated part to build.

The hinges are good but came with no instructions so installation was difficult. Once installed they worked well. Soft close and spring open. Great for overhead pop up cabinets

These are a bit of a struggle to open. This is the first time I have used this type of hinge, it does not come with instructions so I had to research how to use. Otherwise I would have given a five star

I used these hinges to make a top opening cabinet. I would have preferred to use button head screws, but the ones that were supplied work well enough. I like the soft close function, it is nice not to have the door slam every time we close the cabinet. Just a note, whenever the doors close, the hinges cause the doors to move backwards a little bit. So, if you think you are setting a tight gap between the doors, it might turn out slightly different than you are expecting.
