If it is falling apart that badly, and according to one of the previous posters, the manufacturer is NOT very accommodating, look for a different unit, preferable a different manufacturer and dealer.
Unfortunately many of these manufacturers are so concentrated on pushing out new units, probably most as badly made as yours, that is what you get at this price point. When manufacturers put their whole efforts toward new low cost units the consumer suffers.
