It does save time and is much easier on the hands. Have you used it once the bud are dry. I've seen Tom's tumbler but
never used one. Haven't found an affordable automatic trimmer. I have one like you pictured but it tends to shred up the smaller smaller buds vs hand trimming.
all i can say is grow bigger buds. buds where well dry curing before the cut and store.. i was lazy to get going on it
i have so much pot all over now..
