I bought my keg kit from them about 8 years ago. I bought the kit that goes into an existing fridge. When I needed a larger CO2 bottle, I went back to them.
I have had no issue. Installation of the kit was simple. Open box, drill hole in door, mount tap, connect lines and go.
When I was on the market, I looked at a few different web sites, this was the best and most reasonably priced kit I could find.
I highly recommned them. I just started brewing and haven't looked to thier site for any home brewing equipment, but the keg system I got from them has worked fine for me over the years. no issue. one thing I recommend though to anyone putting in a system is to maintain 2 x CO2 bottles... one large and one small spare. Nothing is worse than having a party a full keg and running out of CO2.
