Received it on the Friday - 8 days after ordering so right within the delivery estimate - and used on the Saturday and Sunday. The larger wheels with rubberized tread really reduced the bumps felt going over uneven surfaces and having brake lock controls in front and at the grips in the back really helps lock the chair in place for the patient to get in and out of the chair safely. Expanding and collapsing the chair was relatively easy and the chair is not too heavy to be loaded into the back of a vehicle.
