I should heave got this before my dynavap. I may have been more satisfied. As it stands, this is a perfectly good 510 atty, which does what it says in the tin. It’s well made, easy to clean and you will be up and running in no time - just load the bowl, crank up the heat (on your TC or wattage mod) and go. The whole problem for me is that....I can’t be bothered . I use my mod for regular ejuice consumption and swapping it out and changing all the settings is just a hassle. I have found heat up time to be a little slow too. It will of course get there, but by then I’ve sort of gone off the idea. This kills a 18650 in no time too. You need good 6/7 second presses and you can just see the battery die before you! This works and will be a good, cheaper solution if you already have a mod and want to convert to dry herb. But personally , I don’t think I will be reaching for it often!
