Product review (5 stars): Works well
UPDATE: with a little practice tapping becomes easy.
I am going to order a second one soon.
I can fit up to 3 1/6th BBLs in my Kegerator and I am going to add a second 1/6 BBl along with my home brew soda keg.
I have upgraded my Kegerator to a triple faucet tower with Prtlic faucets. I have Perlic 525ss faucets they are much better than standard faucets.

In theory you can also stack 2 pony kegs using these and a stacking bracket I have seen mentioned in forums but have yet to find the bracket for sale.

Also I added a split ring keyring to the pressure release to make it easier to bleed down pressure when un-tapping the keg.

---------------------------------------------------

Low profile - It does not stick up and has a built in air line check valve.
The only con is it does not have a beer line check valve.
I use with a beer line shut off valve when changing kegs to prevent back flow.
Has barb fittings for both air and beer line connections.
I use a short 6" peace of beer line with a tail peace and a beer line cleaning union and a long peace of air line with a quick disconnect fitting making it easy to switch out couplers and for cleaning. It is a little harder to tap a keg than a standard coupler but the extra clearance is worth it.
