I bought the same hovercraft from a different supplier (and paid more than from Amazon). Its not quite as versatile as the manufacturer describes. It handles very nicely in the bath (the easeiest way to test it in water) & positively burns around smooth lino floors or polished wood/laminate surfaces. Left/Right steering is controlled by turning the two rear fans on or off. Both are very powerful & you feel a real blast of air coming from it. Its not the most accurate way of steering & you usually get huge oversteer which makes it skid about a lot... this is actually a good thing as it makes driving much more fun.
Unfortunately the skirt design is quite crude & generates a lot of friction. As a result it won't move at all on carpet or grass. Basically if your house mainly has wood floors, you have a sqimming pool or you have private access to an ice rink, bowling alley or anywhere else with really smooth low friction flooring then get this hovercraft- its far more fun than an R/C car. However if like me your house is mainly carpeted don't bother because it won't work at all.
