I don't recommend spending money on this. It is not clear why Xiaomi spoils its reputation with such stuffing. You can't just put 0 here, so 1 asterisk. PS. I lay down for 8 months and began to work, holds a charge, spins normally, a good moment, I can’t logically explain how this is possible, and I previously charged with different chargers 1.5A and 2A, and 3A apparently did not hold a charge.
