In use for a little over a year. from the good: - in the pipe mode lasts for a long time (40-60 min) - charges pretty fast - Convenient center of gravity. Otherwise, pure China. From the first days it creaked like a rattle. After a year of use, the wheels began to fall off (the plastic just wore off), they cannot be replaced or repaired. Today it stopped working altogether. blinking red lights and all. won't turn on or charge. in the scrap. For a price of 20+, to work a year with a penny, in my opinion, is quite a bit.
