What Customers Are Saying
The reviews present a mixed sentiment about the product. Some customers found the hinges easy to install, adjust, and effective at closing doors securely, while many others encountered significant issues. The main problems reported include extremely high factory tension, inability to loosen the tension, hinges breaking or losing tension after a short period of use, and poor quality and durability, especially for heavier or solid core doors. Several customers also noted unclear or unhelpful instructions. The reviews suggest these hinges may work well for some lightweight, hollow-core doors, but are not suitable for more demanding applications.

Not Bad!
I do like the hinge. Adding tension is easy. Not really sure about taking off tension. I see alot of videos that say remove pin to add or take away tension but on this particular model not sure. I also read that to take away you need to apply downward pressure to release tension. Can someone please help? Model N351-015

Not good
The hinge is not good. You can't relief the tension.

Worst hinge I've ever worked with
I bought this for my door. The instructions suck, the product sucks, the tension sucks. Just don't buy it.

Less then 6 Months
Bought 2 and installed one to replace old one with a broken spring that had lasted about 15 years. Put 3 clicks in the new one and the spring broke in less then 6 months. Instructions say use no more then 6 adjustment clicks. Installed the spare I had also purchased in January of 2023 today so will see how long it lasts.

Does the job
Fit well where the prior hinge was and does a good job of gently keeping the door closed. Struggled a bit to get the screws in on the door side bit I think that was more my own inexperience.

Low Quality
Looks great, works ok, till you try to adjust the tension. Spring mechanism immediately broke with no effort.
