Doesn't work
We love gravitrax, but this hammer doesn't actually work. Even the simple example circuit included with the hammer assembly instructions doesn't work - the hammer slows the balls down rather than speeding them up meaning they can't climb even the very shallow slope illustrated. Very disappointed little boy.

Works really well!
Worked perfectly for me! Speeds the ball up and therefore gives more options and momentum for your set. Definitely recommend.
