Zip’r Roo 4-Wheel Scooter

Well designed product

Product works great. Really like the fold up features. It is compact for traveling. Maybe not possible but lighter would be better. Would have been nice if there is a storage bag for the walker. This would allow walker to be more easily transported.

Excellent Scooter

This is the second Stand N Ride scooter I have dealt with. I like it. My son likes to use it with the seat. I prefer to stand. I have arthritis in my hips and cannot walk more than a short distance. This scooter lets me get around- on the lawn, up the dirt road to the garden, up the driveway. It lets me stay active. The scooter is powerful, and potentially quite fast. It bogs down in sandy soil and takes some skill and balance to ride standing. - My son uses his in the hallways of a school, with the folding seat. It does very well. The purchase was straightforward, delivery was speedy. The support was quick re questions I had. I would get it again!

Great chair

Better than I expected,what a difference from a 40 lb chair to 24.
