Ok.
Blades and Madd are the same company, blade bought Madd a few years back and used the same design for the Madd scooter as the blade.
Although it is the same design, the newer blades and Madds are extremely easy to break, i've had an Old blade for 4 months and only just broke it, when i did i got a new blade and broke it in a week,.
I wouldn't reccomend riding one unless you can get an old blade.
