Easy to install with all necessary hardware to adjust the hinge and close tension.

These auto close hinges are very sturdy and well made. Works perfectly well and was a perfect fit for my existing old hinge. Comes with both wood and metal screws, along with everything needed to set the spring.

As for instructions. No squeaking sound. Easy to adjust and string enough to use 1 per door in a weather protected pen.

Same general pattern but off by. Over priced hard to use and adjust tension force.

Built a toy box for granddaughter. Closes nice and soft. Won't slam down on the granddaughter. Hardware comes with a hex wrench to make adjustments now and in the future as the hinge wears. Smooth and easily adjustable.

Lid soft closes to about 45 degrees and then slams shut. After that the lid closes as if nothing is holding it up. Construction is flimsy and even after adjusting the tension it is no better.

No installation instructions, just dimensioned drawings. Instructions are horrible to navigate. Directions are microscopic and useless.
