I have the Ascent and I don't have the Crafty. They seem to have some similarities, like they both can be used while plugged in and you can select the exact temp. I've heard the Crafty has good flavor like the Ascent and a fairly large oven. From what I read about the Crafty there are a lot of differences too. Sometimes it's appreciating each vape for what they have to offer.
Think about your needs and price, do your research and jump in. Often it's a gamble, you won't know until you try it out. The Crafty is expensive for a portable that's one of the differences. The App is something the Ascent doesn't have either, also no USB port. To me it seems like the App is something you really don't need. I personally wouldn't want to hassle with it. At first I thought it might be a good idea but I've had second thoughts.
I like the Ascent because you can select the exact temp that you want and it has excellent flavor. A very nice looking portable that fits easily in a purse or a bag. It doesn't look like a vaporizer either.
Im anxious for the spacer that Davinci says is coming out soon. It does have a large oven but you can use something to partially fill such as glass beads or the glass flowers, that is what some of the FCers are using. The small glass flowers are hard to use on the go for a spacer because it's hard to switch out herb. Brand new the Ascent had an hour and a half battery for me but my Ascent was one of the early ones. Not sure what the Crafty has? I've had my Ascent for a year and a half. I don't use it all the time now.
I have several portables and my Solo is my favorite. It's only around $150 or $160. It gives my vapor superb flavor, not stealth though. It hooks up to several different water tool set ups.
Always remember to Fuckcombustion.
