Pros:

• Portable Roller skate which is kind of LOL
• Faster than you walk
• Great Design

Cons:

• Can only run in plain and flat streets
• Not suitable for rocky roads
• Expensive! ($1299!) Better buy an electric Skate Board

Overall:

The Design is Great and Innovative (9/10) , but its features would be around ( 2/10 ) I give this a rate maybe 3.5/10 . Cheers! Nice hunt though.
