Most useless products in skateboarding history!

I don't know where to start with this topic...
          

SKATEBOARD LEASH

So apparently skateboard leash makes your board control better. How? Yea if you don't do any kind of flip tricks... Plus some people use it to take their skateboard for a walk like it's an animal.

SKATEBOARD PADDLE 

Wait... why? Skateboarding is not rowing... You have your legs to push and loose your trucks to handle corners. Congrats if you have one of these, you wasted your money successfully.

PHANTOM LIGHT BOARD

Looks like someone played too much Need For Speed: Underground 2. I mean seriously after couple hours of riding, that lights gonna be dead anyway... On the first sight maybe looks interesting but when you think twice about it, it's totally useless...

WHEELBONE

It prevents your skateboard from moving... If you are learning basics like ollie, kickflip and heelflip just put your skateboard in grass and do it! You can't learn backside or frontside flips standing in place you need movement...

... anyway I don't have much to say about these products they left me totally speechless. No comment.
