charged quickly, worked nice right out of the box, I highly recommend it.

Love this grinder, Perfect compliment for the vaporizer.

Works well for grinding those densely packed fresh buds. Cheap electric grinders just knock those buds around the chamber, but the Quant grinder makes quick work of the toughest materials. The battery seems never to run out as I have used it daily for about a week and saw no discernible discharging. All in all a great value, but i gave it only 4 stars for the following reasons:
1. Chamber is very small and large buds need to be broken up into smaller pieces to fit.
2. Due to the small size of the chamber, the propeller often hangs up at the start if too much material is loaded. The motor does not have enough torque to overcome this.
3. Sometimes it takes two or more tries to completely grind materials. It helps if you shake the grinder as it works.
4. Chamber is often difficult to empty due to finely ground material collected on and around the prop. The included brush comes in very handy, but don't lose it. Also, make sure you empty the chamber over a tray.

These are all very minor flaws and only collectively detracted from a perfect review by a single star. This grinder makes it fun and easy to prep your smokables, and for the price, I highly recommend it.

Love this thing
