Its weak poins:
on old slides carelages evil, see no more at all advance
Charging time is very long and more than 3 hours discharge in 1 hour, suddenly a piece of 45m2, it has to be done in two stages, so it starts in the morning to finish in the after noon.
No one picks up the hair and dust but you tell me, c that's why it is designed!
I m atendais has a faster and more efficient product, shame because I like its price and ease of use, for the price it is a product rather sympat. A real effort in the baterie would make the product more interesting.
