I didn't put any money in the grasshopper yet but I'm anticipating the grasshopper release. I probably would have bought it instead of my E-Nano (which I truly love) if it was already out and had good reviews, because I prefer portability but wanted 100% convection. Even now with the low price on the site, I'm may buy it after reading the reviews and watched a couple of usage videos. I'm a convert to convection and I'm looking forward for a pure convection portable vaporizer (with temp control). Hopefully July 2015 is the D-Day (or the M-Month) as I can see on their website. Stealth, small size, convection, price. Very tempting. Can't wait for the first reviews of the final product.
