Product review (4 stars): Go for it.
This thing works exactly as one would expect. There is one drawback - the supplied tank is not the standard size that companies around where I live use. So I still had to get a slightly larger tank in order to make the exchange easy. It fit inside the kegerator but the strap would not fit around it.
Another thing to know about this thing is that it keeps a decent amount of its resale value is easy to sell.
