CAUTION - BUYER BEWARE
The first 2 reviews of this product are correct. Although this product has a rugged design, the pivot points are riveted with steel on steel contact. After installing the unit the first problem was that it wouldn't allow the gate to close all the way unless you adjusted the hydraulic cylinder to the point where the gate would slam defeating the whole purpose of the unit.
The second problem came after several days of rain, the pivot points which were riveted together began to rust and the unit would not close at all after opened unless forced. A better design would be to at least place some type of nylon washer between the steel links to allow them to pivot easier.
So unless you don't mind making modifications to something you just purchased to make it better, look elsewhere.

Not For All Doors
We installed this on a wood frame door and after a few days the wood began to crack on the frame. This product is made well but is not as the package states "for all doors".
I do not doubt that it would work well on an all metal frame door or metal framed gate. The key issue being that the door frame should be able to withstand the compression of the two very powerful springs that the Kant-Slam uses to close the door, upon opening the door these springs compress, and require the frame to be the opposing stress point to push against.
Its a little difficult to describe how the Kant Slam functions and the company ([...]) would do well to create a flash video to allow potential users to see it before purchasing.

No problems
This unit installed and worked flawlessly. It is a bit retro looking (but kind of nice in that way). It must be installed carefully and a bit deliberately (easy on wood and a bit more difficult on metal) to assure that it will work well. In regards to the reviewer who had so much trouble, I belive that there must have been something wrong with the installation, alignment or adjustment -- especially if it resulted in bending the heavy iron hinge unit and pulling out the mounting screws. This item has been manufactured since 1927 and they are widely sold -- so I took the leap even after reading the negative review and I am pleased with the result.

Ugly and didn't work reliably
I have a gate to a children's play area in my yard. My kids are always slamming the gate and I cringe for little hands or fingers getting caught. I thought this might be the ticket. How wrong I was!
It's huge and ugly, clashing with my nice cedar fence and gate. OK, I was willing to go with it, assuming it would do a good job. Sadly, it was very hard to operate. My kids struggled to open the gate and it didn't always close all the way. When it did close, its closing motion was not smooth. I finally uninstalled it when ripped the screws holding it out of the wooden gate post. Upon inspection, I found that the mechanism had bent due to the force required to operate the gate with this installed.
