I've had a Lee Ergo Prime I've had for about a year and keep having trouble with small primers. Looked for fixes, watched videos to see if I was doing something wrong. Hated to send it back since I'd be without a priming tool while it was repaired but I finally broke down and contacted Lee. Apparently I wasn't the only one and got a response saying they'd redesigned the small primer feed and they'd send a new one in the mail. Probably still won't work as good as the old ones, but you gotta love Lee for their customer service.
