Product review (3 stars): A good system if you don't mind doing a little work.
First of all, this item was packaged horribly. It arrived in a cardboard box that looked like it was giving birth. The taped seam was bulging and there was wadded up paper (used as packing material) sticking out.

The nuts for the back of the shanks are very thin. They really need some large washers to work properly, but none are included. Also, the fittings in the regulator were all loose. I tightened them up, only to find out that they still leaked. This caused me to waste basically an entire bottle of CO2. I had to remove all the fittings and add Teflon tape to fix the problem.

It seems there is also a bit of a mystery as to what you'll get with this kit. My buddy bought the same kit and received a few different parts than I did. He got a slightly different regulator (that didn't leak or need modification). He also hit plastic, clip on style hose clamps whereas mine were metal.

I'd buy the kit again, but I'd have lower expectations than when I made my initial purchase.
