I bought a Mighty in November, I've used it every day since and it doesn't let me down. I had the battery-never-showing-full and not-being-able-to-use with-a-flat-battery problems, but other than that spot on.
I did find it a bit big though, and after a few months I felt like it would be nice to have something a bit smaller. So, for a backup I decided to get a Crafty 3 weeks ago. I have been alternating use with the Mighty and I'm slightly disappointed.
The thing is the battery. I always pack out the bowl to the max and just vape until there's no more. This can take me a good while in the Mighty, something like 30-45 mins at a leisurely pace which I enjoy immensely. The battery goes down by two bars maximum then I stick it back on charge. I only vape at home bear in mind, I'm not an out and about user.
So I tried the same with the Crafty. I'm rarely able to absolutely finish the bowl in the same way as the Mighty before it goes flat. On the Mighty I do 190c until the vapour thins out, then it's max temp until completely spent. On the Crafty I set the same temps, and not long after boost it dies. Every time I'm still pulling pretty thick clouds so it's pretty annoying. It takes forever to charge so by the time it's ready to go again your material has cooled and you don't get anything else out of it. I've put it at a bit lower temp and it's the same experience. Using it felt like a race against time before the battery ran out.
I remember thinking at first it wasn't performing as well as the Mighty, but I think it just needed breaking in. It does produce lovely clouds just as thick as the Mighty. In my opinion though, the Crafty is marginally a harsher vape. I guess it's the shorter vapour path, I don't know, but the Mighty came off as a bit smoother.
The Crafty IS the right size for a vape though. It doesn't feel quite as sturdy as the Mighty with all the fins, but it's nice and lightweight. It's very comfortable in the hand, much more so than it's big brother. The bluetooth connection is bloody marvellous. I like keeping track of my usage, 21 hours in three weeks and that's alternating with the Mighty. The lack of temperature control didn't bother me too much, I only use two temps on the Mighty 90% of the time anyway.
I think it's only real failing is the battery. I don't think it's suitable for my vaping style. Smaller bowls and just hitting it as hard and quick as possible would help get more out of it I reckon. I was thinking when I bought it I would use it more than the Mighty, as it's definitely more pleasing in a tactile sense- the experience of holding it it just nicer. But that damn battery. I just can't finish a whole bowl, even when it's charging while you're using it. And good luck doing that with that USB cable! I've seen longer earthworms! And be wary thinking you can use an Apple plug- I tried that and it took forever to charge. I think so anyway. Maybe I was just being impatient.
All in all, I would say if you are weighing up whether to get the Crafty or the Mighty, I'd say Mighty hands down. The Crafty battery just didn't cut it for me, and the slow charging times are painful. After using the Mighty, I plug it in and it's full in no time, Crafty is always completely dead and takes 2 hours to fill. And the Mighty can actually charge full when you're using it.
It'll do as a backup vape. I bought it from Vapefiend but I'm pondering whether to ask S&B if I can pay the difference for a Volcano.
