The product seems good but I installed and then uninstalled it. It鈥檚 for my mother. The fitting of the arms into the base plate at the rear is not a good fit. It鈥檚 shaky and tends to wobble. Also the rubber feet tend to slip. Didn鈥檛 have confidence in it. Wanted to return but 麻豆区 gave me a full refund without having to return. Bought another brand from the local market.
