I ordered a riser kit for my 25 year old septic tank - NOT going to have to dig ever again! I like the fact that it's made in the USA. The kit was super easy to put together. All of the pieces were exactly as described in the instructions and everything fit together perfectly. It did take us longer than an hour to install only because our battery kept dying on our cordless drill - concrete gets harder as it gets older. The finished product is quite attractive as well as unobtrusive. It will be nice to just unscrew the cover rather than digging a hole every couple of years!
