The only thing we dont like about it is we got the model without the electric motor. We are saving pennies atm to buy the motor that goes with it, arm gets tired after awhile. As for waste, there is basically no damage to buds but just watch what your doing. The trim that ends up in the bottom can be dried and preground for cooking or even mixing in with crushed bud for smoking. Everything else into the bag and ice water :thumbsup:
