Just picked up my first pen style vap and should have gotten one long ago. It's awesome for stealth fits in my palm, simple to use. The main reason I wanted one was so I could smoke the hash I makes. And the sleek works great for it with the wax cartridge and also comes with a dry herb cartridge. Haven't tried dried herb yEt. I bought a extra dry herb cartridge so I packed it with hash and works great. The Death star hash I made taste so much better vaped fresh lemons and was medicated for 4 hrs without feeling paranoid like I usually do with the death star it's so strong. Can't wait to try my strawberry diesel hash today. I am sold on the vaping so easy and I recommend the whiterhino sleek to it small fits in your palm so it's easy to sneak tokes love that.
