Product review (3 stars): Multiple issues
The first issue I had is that I didn't receive the Sanke keg coupler with the kit.  I went ahead and ordered a replacement so that I wouldn't have to wait to resolve the issue with the supplier.  I then proceeded to hook up the rest of my equipment so that everything would be ready when the coupler arrived.  I then found that the regulator didn't work.  With the pressure adjustment reduced to the minimum setting, the outlet gauge pressure continued to rise until the blow off valve relieved pressure.  The pressure would continue to rise and blow off in this manner continuously.

HomeBrewStuff sent me my missing tap by priority mail and I was eventually able to get the regulator to hold pressure after cycling the pressure adjustment.

I did later hear a leak on the tap which I thought I fixed after removing and re-seating the tap.  A few days after this my CO2 tank was empty.  I refilled my tank and sprayed the tap with soap water to test for leaks.  The tap was leaking from between the tap stem and tap body.  I disassembled the tap and found that the stem o-rings were misshapen.  It appeared that the valve was assembled without any lubrication causing the o-rings to twist and leak.  I lubricated the o-rings, reassembled the tap and tested for leaks.  So far I haven't found any leaks but I make sure I don't leave the CO2 on in case it begins to leak again.
