Really good bottles! My only complaint would be the small spouts for the carb drops and the filler tube thing. I actually got the end of the filler stuck in a bottle and had beer going everywhere. Was still fun, just used some tweezers to get it out. But make sure you put a towel or something down when bottling. I also think while the plastic were a bit easier to fill and are recyclable, the glass would be a better buy if you planned to do more than one brew being reusable and the beer will last longer in glass.
