Add my two cents to all the negative reviews. I have experienced all the problems listed by others. Lid not secure; rod doesn't align; primers flip in the tray; tilt unit to feed primer into shell holder & the shell falls out. I have a 20 year old RCBS hand primer feeder that has worked like a charm for thousands of reloads. "If it ain't broke, don't fix it." Addendum: it's 13 weeks and no rebate sent. I wrote them and they couldn't care less. Their reply: It's coming, soon???

Ex Output:
negative

Ex Input:
I purchased these for my sons birthday and they were a big hit. The kids loved all the tricks but the one that got the least interest was the calculator trick which was stickers with numbers. It may have been a good trick but the kids passed it by and they were the last ones to go.

Ex Output:
positive
