Purchased this chair due to the recommendation of my physical therapist who said I should upgrade from a upright walker to an electric wheelchair because of my severe back pain. I had some concerns about purchasing such a large item over the internet but after speaking to the allstar wheelchair support team they quelled all my fears and 3 days later my wheelchair was at my doorstep! Needless to say I have had this wheelchair for several months and I am more than happy with it it makes the usual 10 minute journey from my driveway to my doorstep with my walker take only 10 seconds with my electric wheelchair!
