The only thing I wanted from my Defender was for the batteries to last a lot longer than my mini and standard KR808 auto bats. Being quite the newbie at vaping, little did I know I'd end up getting soo much more!
1. Warmer, smoother, easier draw (using turbo cartos with Defender as compared to same with the auto KR8 batteries). Before a lot of TH's could feel rather harsh and I thought this was normal, but I've not had one harsh hit from the Defender soo far.
2. Didn't think I'd like the size of the unit (shorter length was never an issue but being soo much bigger around was)...well, this fits in my hand VERY nicely and is a lot smaller around than a dime, and it doesn't seem heavy either.
3. My first battery lasted me 7 hrs. today and was still going but it seemed a bit cooler vape so I assumed it was time for a fresh battery so I changed. Maybe I should have continued vaping just to see how long it would go.
4. I don't take long drags so can't give a good detail on vapor...soo many variables can go into that as well. Plenty sufficient for me, though.
Downsides.....
1. Seems I either have a thread issue or maybe this is common with e-cigs that have cones, but I have to put the cone on first then install the carto for everything to fit right. Otherwise, I can't get the cone to screw on all the way. Cosmetic issue only...nothing major as I see it.
2. Not my fave color combo but will gladly live with it with everything else it has given me!
Thumbs up, Ben, and thank you!!!!
