[Q]: This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.
[A]: Positive


[Q]: 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.
[A]: Positive


[Q]: This lunch box was actually too small and too flimsy to be used as such. My grandson puts Disney miniature cars in it, instead. Once he filled it up, the latch would barely stay closed in order to hold the contents. Basically, it's a cheap piece of metal with Disney Cars painted on it to justify its price.
[A]:
Negative
