I couldn't agree more. I was ecstatic when I saw this at the local TRU, so I
bought one. Probably bought the FIRST one. The "programmable" brick did
NOTHING like I had recorded it to do - time after time. Went too fast, didn't
rotate to the proper angle, didn't go the right distances. I am definitely not
going to recommend this set to fellow AFOL's. IT may be fun for the actual
target audience though. Now mine sits on a shelf collecting dust. I do like
the gearbox piece ideas, but have not even touched them (or the ones in Motor
Movers) for fear of getting lubricant on the rest of my collection..
Take John's advice (and mine). Don't buy this set for what it was intended to
do. Buy this set if you need/want some of the parts it contains. Now it gets
Barnes and Hendrix two thumbs down.
