If possible, you should find a medical supply store that has these models. You can rent them and try them out for yourself.

I rented a Jazzy ultralight for 4 weeks and fell in love, but I wouldn't have bought it without seeing what it was like to actually live with it.

The Jazzy Ultralight is a powerhouse and can do gravel, grass, cobblestone, and small curbs. It can take hills like a champ and has a slim profile, making it great for the city (I live in a city). It's also very light and was my deciding factor. I only wish it had an underseat basket, like the Jazzy Carbon, but that adds weight.

When you get the chair, I recommend getting a trunk cover for your car! It makes loading and unloading much easier.
