It's good you scored the loader, because the strips are first to be gone in times like this, so stock up! The unit is ok, but mine, if I short stroked it, and let the strip advance, but didn't seat the primer, big mess, I had to disassemble the thing to get it back on track. I didn't like it and gave it away, bit the guy who has it, loves it. Lots of torque!! The handle was way too long, and if you have a high bench, it's a pain.
But you may find it the next best thing too canned beer, so take my rant with a grain of salt.
The hand priming aps tool works better, but being spring loaded, puts some wear on your hand that the ordinary one wont.
The only reason I ended up with the stuff was I have a Pro 2000 press, and aps was the only option to prime at the time. I've watched the guy use the loader, it didn't look any more time consuming than flipping primers in a reg tray, so.
Try it, you may like it, and you might as well before dumping it.
