I have just returned the new Bohning to the shop for a refund. First impressions was that it was a cheap toy, the motor was no bigger than my fingernail and the little plastic wheels wobbled like a toy cars do.
It started off ok and I managed to crest half a dozen arrows although the arrow needed kick starting to get the motor to turn but the tiny speed control lasted for just those 6 arrows before it gave in and went on a go slow. Obviously the circuit board went crazy on the one I received.
This could be a one off and I received a bad apple, but in my opinion, after paying £150 (Over $200) it was definitely not worth the money, even if it hadn't broken down.
Of course, many people will be very satisfied with theirs, it's just for that sort of money, I would want a machine more rugged
