I found Slim's app on Google Play. I checked it out to see if they had a drip line, and sure enough they did. I took a chance, and ordered a 50 ml bottle, because it was only $25. I forgot to put in the 20 percent off coupon code, so I emailed them and asked could they just hook me up with a few samples. They emailed me back promply, and said "sure." I got my package in and they sent me 70mls worth of samples! To top that off, all of the juice is definitely top shelf. Give them a try, I promise you won't be disappointed. They are definitely in my top 5 vendors now, and I am VERY picky about my ejuice.
Edit: I wrote this review before I tried the juice. Out of the ten sample bottles that was sent to me, NONE of them were vapeable. I tried steeping, and still they were awful.
The one "premium drip line" juice that I got from them wasn't horrible, but definitely wasn't great.
Another major turn off with Slim's juice was it would turn the cotton a burgundy red, and gunk the coils overy horribly after 2 days of use(I never made it two days but my wife seemed to like a couple of their flavors).
So in conclusion, Slim's has EXCELLENT customer service, but they need to put a lot of work into their juice.
