I bought one of these a little over two years ago for loads that I wasn't dropping with the Dillon 550B powder dispenser. I had read so many negative customer feed back reports on the RCBS and Lyman auto dispensers concerning failure, warm up time, static, over charging that I decided to try this one when it first hit the market, it was a little less expensive too.
These auto charge machines are like a third hand. They drop a charge while you are busy sorting, seating, crimping, packaging, etc. They are a huge time saver.
Overall I've been pleased with it's ability to dispense any powder I've tried with reasonable accuracy. It's adjustable with three dispensing speeds to accommodate the powder selected. It auto trickles and starts the next charge when the tray is placed back on the machine as long as the previous charge was not an over charge. If it was an over charge it will beep and require you to hit the reset button prior to dispensing the next charge. Generally selecting a slower final trickle setting will solve a future overcharge condition.
I've not counted the loads I've thrown with this machine but estimates based on the ammo I've shot personally, the ammo I've made for two competitive shooters, cousins, brothers, uncles, neighbors, friends it quickly exceeds 8,000 charges over the past two years.
I right this thread basically because of the great customer service Hornady recently provided. A little over a week ago I went out in the shop to load up a recipe and the machine just made a hmm sound followed by a few clicks. I called Hornady and they immediately emailed a return authorization and a UPS label for free shipment back to Hornady. I taped the label on the box on dropped it at a UPS drop site less than 2 miles from home.
Hornady followed up with an email saying they received the dispenser and a tracking email saying they had shipped a new one out that same day. Now less than 10 days from the initial call I'm sitting in front of a brand new Lock-N-Load dispenser, no questions asked, no hassle at all. They didn't waste my time with a repair job, just a sparkling new machine.
The amazing thing is this product was registered when I bought it and it's clearly beyond its one year warranty period, They replaced it anyway.
