What I've learned is the cheap tanks mute the flavor. Many times its the yucky tastes that's being muted. You think you like it. Then when you get home you taste something that was muted before but is fully tasted in your better tank. I've experienced this quite a bit. I've been making my own juice for months now, but I love buying new juices too. It's hard to test a juice in those cheaper tanks because the horrid bad tastes in some juices are muted until you put them in a Russian or Kayfun or a good dripper.
I bought Halo TriBeCa from one of my local shops. I tested it in a CE4 tank at the store. It was delicious so I bought a 30ml bottle at a little over $20. I got it home, loaded it up in my Russian and I still get the good taste but this horrid taste also. It's not steeping. I ask the shop owner before I left how old was this juice. It was over a month since he received that shipment. Plenty of time for steeping. I've had it for 3 weeks and still get a horrid taste. I've tried it in my drippers, Kayfuns, Taifun FT, and my fogger. All tanks taste the same.... It's those little cheap tanks muting parts of the flavors. You get home and boom you get hit with all flavors, the good and the bad!
