LINSHI Spring Door Closer, Quiet Automatic Door Closer Adjustable Tension Door and Easy Install Auto Door Closer for Self-Closing, Perfect for Home Use(Black)

This work God on my storm door

3 stars because of the functionality.I would not say it is for commercial use, has installed on walk-in freezer door.Needs to adjust spring door closer for few times after couple days of work,because of the not enough powerful spring, it doesn’t close the door completely

This little unit is very powerful and does a Great Job on closing the Door I installed it on. I would buy this again if needed,

They work good, I’m happy to have them

Can not install it because of missing parts

No instructions. There is an arrow on the barrel of the devise, but nothing to tell you witch way it should point.

Absolute junk.worked for one time and that was it.

Terrible product and instructions

El producto cumple muy bien, solo sería bueno poner ajustar la dureza, si embargo se adapta muy bien a su propósito.

Easy install, works great !

Pretty decent product, it works as advertised. Only negative thing I have to say about it is that the metal plate that they provide is a bit short.

Efficace

Makes an awful noise. Mounting arms do not fit properly in their sockets (poor machining). ...and the whole thing does not close the door unless I crank it to the point where screws come out of the door frame given high internal friction of the mechanism itself.
