Just a little curious at what juice you've been most disappointed in. Whether it was from one of your favorite vendors or from a DIY mix that came out absolutely awful. My worst is from my local shop like six months ago, the juice from there had always ranged from alright to real good The flavor was guava, I remember when I went to hit it, and after the second puff I was hating it, by the fifth I felt like I could puke. Threw it outta my tank and changed the coil. Been too scared to try any guava flavor since.
