I'm not usually a hamburger person, but I really liked these. They were very moist and tasty. I followed the recipe exactly, except that I cut down the horseradish a bit. Next time, I'll use the full amount: while it smells strong in the raw burgers, it wasn't at all overpowering. Also- left the meat (90/10) in the fridge until the last minute and the burgers stayed together nicely while grilling.
