Not a good quality in the first day of use the handles became loose.
The chair was heavy and cannot be operated by all as showing in the pictures and video.
when it climbs or goes down the stair someone need to keep it at the same angle to reach the steps.
It humps during movement and give uncomfortable use as expected.
I will not advice to buy it online and better to buy it physically so you could give a good judgment by yourself before purchasing.
