The G Pen Elite is Grenco Science's crowning glory. It offers unbeatable performance for the size and price. This is an evolution of everything they have given us in the past. The heating chamber is all ceramic, meaning you get perfect, pure, uncontaminated flavor no matter what and the combination of convection and 360 degree conduction heating really helps make the most of your dried herbs. The chamber is massive for a device of it's size, holding up to 0.75g of material if you really pack it tight so you can have a really long session on one fill up. There is no waiting around either, you just turn it on and around 15 seconds later it's up to temp and ready to go. The battery will give hours of use between charges thanks to the devices efficiency and you'll never be caught out because the full LCD screen contains a battery guage to tell you exactly what state your battery is currently in. Even when it does die, you won't be caught out because the micro USB charging lead allows you to charge it anywhere. This really is a super simple, super compact vaporizer that packs a powerful punch well above it's weight.
