Before buying, I used the same one for about 4 years, only wired, completely satisfied Experienced a lot of throwing on emotional grounds😅 Outwardly, nothing differs, except for the wheel, which dangles a little, although it doesn’t bother me personally I heard reviews that it was too heavy, but the first thing I put in it was a couple of weights In general, I am satisfied with the purchase, the wires are tired. It remains to purchase a complete mat with charging
