High-performance product, suction is very powerful if complies with the charging instructions before use, double filter system adequately protects the engine block, appliance purchased to replace another vacuum (3.6 V power) significantly less powerful. Dark and subdued colors perfectly suited for this type of device. As always the order managed by Amazon is properly treated, good price (I have searched a lot in supermarkets and electro-domestic stores near my home without success), secure payment and debited only when sending the parcel, parcel that is impeccable, the product is very well protected, short but positive !!!
