I use it, but I'm very new to brewing. I followed all the recommendations among the various threads on this forum and didn't have any issues.
I fill one 6L during bottling, then put the rest of my beer in glass. My last batch used one 6L TAD bottle, 18 12-oz bottles, and 6 larger bottles of various sizes (22's,16's, etc.) Using only one 6L allows you to keep brewing as long as you have enough glass. Another dispenser tap and TAD bottle set is in my very near future because I don't have that many bottles. With 4 kids, I don't like having lots of glass around the house.
I use the TAD because I didn't want to jump right into kegging. I'll eventually get there, but this is a good alternative in the mean time. I've even considered replacing the short dispensing tube with a much longer length of tubing and installing a tap through the door of my mini-fridge. You'd just have to leave the dispensing valve open on the TAD tap. Might work, might not, IDK?
