I purchased this knee scooter off of Craigslist after breaking my ankle this fall and realizing that trying to do anything while on crutches was maddening. The scooter - and especially the basket - was a game changer for me.
I only used the scooter in the house and wouldn't personally try it on anything but stable terrain, but around the house, it was wonderful!
The scooter comes with a basket and a bag.
