For the price you pay (approx 21USD shipped in America) for 100ml or 3x 30ml, you can't ask for a better price! The juices I've tried so far have been very delicious, and replications of established food flavors have been near perfect
It took about a day and a half for them to fill my order and ship it, but the next day they were "sold out," so I assume it was due to a high volume of orders.
The juice came in your standard packaging, nice and safe. All juice has a blank label with the logo and nic level, with the flavor hand written on. The label doesn't wrap around the bottle, so you can see how much juice you have left. Bottles are clear plastic and child safe.
The site is kind of tricky and annoying. Instead of adding things to a cart, you have 1 item to add to the cart. Then you pick your nic level and type which flavors you want. I would guess this makes it relatively easy for you to ask for custom flavors. There's no option to get 3x30ml, but if you ask for it, they will do it.
If you've only got $20, and want to try new juice, definitely give them a go! The amount of juice you get for this price is unbeatable, and if you don't like it, I'm sure one of your friends won't mind a free 30ml.
