GraviTrax Expansion Jumper review by Marble Grooves

[@JeremieChallenger]

4:30 to try fixing this you can push the trigger back. This is useful for bigger sensitivities like this one. Each jumper may contain a better sensitivity or may have a similar one.

And your storage is pretty safe. Could be handy because i usually had it in either the box or the bag

[@ed98027]

Can you tell if the jumper is spring loaded it is it a rubber band? How long do you think the elasticity might last with repeated use?

[@meme4966]

It is Mark

[@GravityGroovesByRaceGrooves]

Mark, it is!

[@meme4966]

yes it is

[@kian_23]

Oohh, Interesting, the tunnel Part under it is very unique and cool. I Love it. It looks like the flipper and the jumper is a good combination.😁👍 edit: Sorry autocorrect for flipper, it said flipped

[@kian_23]

Do you think this and the flipper would be a good combination?

[@GravityGroovesByRaceGrooves]

Yes, nice parts to have.
