To say that the Roller Wheel is immense fun would be a galactic understatement. Rigorously tested by my kids who are well below the recommended age (dont call Social Services), the only problem we hit was getting them to stop playing with it & come in for a bath. We didnt use the included pump to inflate it as it would have taken all day, but with a decent pump it was easy. Once firmly inflated you get inside it & roll about like a happy hamster. Suitable for mucking around with both inside & out the Roller Wheel will be your kids favourite toy for more or less ever. Its not recommended for adults, but that didnt stop us re-living our youth, & consequently nearly regurgitating our lunch. superb & simple fun
