Reliability and price! Spin Life is half the price of local vendors (Knoxville, TN) and it is attractive.
external charger is one more piece to keep up with, size is a little larger but makes a huge difference in what I can do. However, I will CONTINUE to be a direct customer -- can't deal with medicare and vendors who do not attempt to simplify the process!
