It beats the shit out of crutches but it's not perfect. Part of this could be because I got a well made, but cheaper model. The wheels are pretty narrow so you have to be careful with bumps, and the turning radius is lacking. The knee pad is pretty cozy though. I can't bitch too much because like I said it beats crutches and this is the model advertised for $120ish dollars at Walmart.com and Amazon but I found a gently used one on letgo for $70 and the fella even brought it to me. It definitely makes trips to the kitchen and bathroom faster and more bearable.
If you use Amazon Prime and don't mind paying full price they can have it on your doorstep tomorrow. https://www.amazon.com/dp/B00I471EI8/ref=cm_sw_r_cp_apa_i_TdTYDbN01HS0D
