Well, idk about this pedal. Never tried UAD's stuff so can't speak for its quality.
But when I got my 5150ii from Japan, the original owner packed it in a single layer of bubble wrap under a form-fitting box (because he thought it was just going to some warehouse in Japan lol he didn't know it was going to an overseas shipping service)... it sat at that warehouse for more than a month, and at some point while shipping overseas, it was loaded upside down, was accidentally dropped at least twice (once by the courier, once by me)...
I literally just unpacked it, plugged it in and turned it up and it worked perfectly like it had always been here. Can't complain
