I bought this for bottling just before I started kegging. This is very quick and simple to use and recommend it as well.
Oh, it's not like the pics, a large amount of starsan bubbles will be coming out, you'll definitely want to do this in the sink.
Be aware that long starsan soaks may damage/remove the paint from printed bottles (red stripe, corona, rogue, whatever). Maybe you want this side effect, maybe not.
