It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.

Positive

Not what I expected, the first Transformers was the best. The special effects was great but acting was not, too bad.

I purchased this Trikke thinking that it would be a great surprise for my son on his birthday. When I received the Trikke it was missing two pieces. This Trikke came in a box that didnt match the product. It does not fold down at all which makes it hard to pack for trips etc... I am very dissappointed in this product and Razor company should get a great big slap for false advertising. The advertisment also does not state the weight capacity, its say both kids and adults can enjoy this product. The weight capacity is only 175lbs. It does not come with an owners manual, and there is no tool case. The allen wrenches come in a plastic baggie taped with scotch tape. Very Very disappointed.
