Only reason I gave it 2, is because it got here on time. Other than that, it cut the skin behind my calves, chair is listed as 76lbs but they don't tell you the battery is another 30+lbs. So if you're elderly, like me, you're going to have a hard time loading in and out of vehicle. Several other issues were noted, seller basically calling me a liar, that no one else had any issues, which I find hard to believe. The chair is wide, which made it hard to get down hallway and into bathroom. They told me to fold the chair and push it! If I was able to do that, I wouldn't need or be in a wheelchair! Also note, it is listed as returnable, but they do not pay return shipping cost which for us, was over $400.Thank goodness Amazon is reimbursing us under there A-Z service. Please think twice before buying from this company named CHEOBAI
