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.

Ex Output:
Positive

I've only worn this for a day so far, but I love it! I still have a little bit of a tummy from the birth of my son 8 months ago. This really holds you in, its comfortable and I don't think it shows through your clothes! I highly recommend!!

Ex Output:
Positive


Ex Input:
Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.

Ex Output:

Negative
