They cost that new and you get a 30 day money back guarantee and 1 yr warranty. Volcano brand is the same type and price. They are OK at best. Some people love them, some hate them. I had the Blu kit and sold it. Reasons for selling.
Battery life is very short. Yes, it has the pack but they go dead real quick and you constantly have to change.
Battery is super sensitive. Wind, breeze, music just about anything made them start. Couldn't use them in car with window down.
The carts taste great for the first 3 vapes...then die out. They did work much better when I re-stuffed with Fluva.
I got the Blu Kit for my wife and we sold it 2 weeks later. I bought her a 901 which she likes better. The Blu's are a good kit as a 2nd or starter, but you will be updating later and for the price other types are better.
I have bought a 401, 510, 901, and 808 to try them all. I switch around to keep me happy, but do not miss the Blu at all.
