Due to a muscle disease I can barely walk. I needed a power wheel chair to get out of the house. My indepence had been taken away. Also, I travel for my career and needed a power chair that was TSA & airline compliant, lightweight, easy to use, and didn't cost thousands of dollars. I shopped for weeks and found this chair. It changed my life, It's strong enough and powerful enough to give me my indeoendence back. It is accepted by TSA and the airlines, no problem. Is lightweigh and easy to use. Also, I didn't have to spend all my savings. It made my life complete again. I can go out and just enjoy the autumn weather,. I can go through the aiport and fly. Uber and Lyft drivers have not complained since it folds up an is lighter than most luggage. It fits easily in the trunks of all cars. The battery is strong and reliable. I love it! It was one of the best decisions I've made to purchase this power chair.
