[4-Pack] Heavy Duty Lid Stay Hinges QBOSO Folding Lid Support Hinge,Perfect for Cabinet,Closet,Wardrobe or Toy Box 110 Degree Heavy Duty Style

Pros:Looks nice installed,Easy to adjust tension on rod.You can figure out where to install the brackets for both armsCons:No instructions for attaching arms to brackets.Attaching the arms to the brackets takes some work, since there are no instructions that cover that step. You can use the 2 plastic tabs to space arm connector to the bracket, facing the narrow part of each tab towards the bracket hole on either side of the arm connection.The hinge works smoothly and looks nice. I'd recommend it since you have a lot of flexibility on how to configure it, and you don't need to measure as you can work out where to drill the holes easily.

The hinge's friction tension is adjustable, allowing it to be tightened or loosened depending on the weight of your lid and the speed you want it to close. I installed it on my wife's 60-year od toy chest, that we now use for our grandkids when they visit. My wife mentioned that she feared the lid could be accidentally closed on one of our young grandkid's finders, causing great pain. On one of the pictures, you'll see the lid has been closed to about half-way, and it stys there until you add more pressure to have it close. This hinge checks all the boxes: attractive, fairly easy to install (after a wooden brace was secured for the bottom of each bracket), adjustable, and unobtrusive (from the outside). Well worth the money.

I was in need of something QUICK because the locking hinge on my wooden storage chest failed, smacking me in the head. This product offered Same Day Delivery, so I bought.When you remove it from the package, it looks okay. Hardware, screws, and allan wrench are included.The instructions look like a terrible grade B movie that was translated from Chinese to English. The written text makes no sense whatsoever. The drawings aren't much better.If you buy these hinges, search You Tube for guidance. I watched You Tube video and chucked all the instructions.I might have sent these back if I were not in danger of a concussion from the lid falling on my head again. So, since I had it in hand, I installed and will use these hinges for as long as they last.The biggest problem is that you cannot get it as tight as you might like with the cheap allan wrench and the allan screw. As I tighted it with the allan the head of the screw and the cheap alan begain to fail. Because of this, I cannot get it any tighter than it is right now. The metal on the allan and the alan bolt head must be made of cheap soft metal.As it is now, It will remain open up to about a 45-50 degree angl from horizontal. As you continue to lower the lid the hinges do not offer any real resistance. I am not going to test this, but I'm pretty sure that you could suffer smashed fingers.If this does not get any worse, this will serve my purpose because I ONLY want it to hold the lid fully OPEN. Even though this seems to release the lid as it gets past 45 degrees, this is not a big concern to me. But, should open/close move the allan bolt, it's unlikely that I will be able to tighten it back up because the allan wrench will no longer get a good grip on the allan bolt.At that point, I'll be looking to replace these hinges with something of better quality.As a recommendation, I'd categorize this as a DO NOT BUY. Even if I had to pay a little more, I would purchase a higher quality product as I'm pretty sure this will not last

They work. Instructions were useless though. I used them on small 10" x 28" doors and got them to work. If you are using them on anything bigger I would go with something different.

This item seems useful for vertical doors only (meaning, a hanging cabinet where the door is on the front, instead of my toy box scenario where the lid is on the top). The hinge is stiffest when fully extended, and then gets weaker as it closes. In my scenario, this means that as the heavy lid comes down, it is difficult to get it to start to close, but then as it does, the lid accelerates to a slam, taking your fingers with it. This would be perfect, however, if you have a vertical front door on a laundry cabinet, however, as the door gets "lighter" the closer it gets to closed. The diagrams in the instructions seem to favor this use case, although it's not clear. Instructions are horribly cryptic. I'm an engineer, and struggled to make sense of them.

Own a wood shop and have used these for several years. They work will for light to medium duty loads. Not soft close. No complaints.

I really wanted to like these. I would describe them as rickety and unprofessional. First of all, they arrived in pieces with no instruction on how to assemble them. Then, in order to install them, there are four sets of instructions that are all different, written in broken English. Literally says "if you find this difficult, then Google it." WOW. Can I get my money and wasted afternoon back?Once they are installed, they don't even match. You have to flip one upsidedown which makes the curve go in the opposite direction on left vs right side. (See pictures). Unprofessional and inconsistent feel when using right vs left mounted hinge. The hinge itself has a lot of play due to plastic parts, and screws that don't tighten all the way. Word that comes to mind is "garbage."I had to use a combination of YouTube, Google, Amazon reviews, and Amazon photos in order to figure out how to first assemble and then install these. Had I known, I would have saved myself the money and wasted time.

I am very pleased with this product. It was a perfect solution for my situation. I converted the bi-fold closet doors in our bedroom to pivot doors by gluing the doors together and eliminating the top track except on the far edges where the pivot pins are. My issue was that the doors would not stay fully open but these hinges solved that problem. I found them easy to install - I did not need or refer to the instructions that came with them. They look nice and hopefully they'll stand up to the daily use of the doors.
