Review on Bilz Lope Puzzle: A Challenging Brainteaser for All Ages by Ted Slaughter

Loved it. I have a wooden box for my son and this one is for my daughter. It took him a while. It took her 2 minutes to solve it. Why? Because I received it with a small metal ball in the final position. This issue has already been fixed. It appears to have been used, solved and returned to the company where upon resale it was simply returned. I will stick to wooden puzzles in the future. Gave 3 stars because my daughter liked the little maze well enough to keep the box. Although she never had to solve it.
