[Q]: I have a small business and it was important that the envelope feeder work well. From day 1, this has been a nightmare. Components of the printer block the envelopes/labels and they don't feed properly. If you use internet postage, you lose money with the misfed labels/envelopes. I'm very disappointed and am shopping for a new printer now, only a short time after purchasing this one.
[A]: Negative


[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]: I often listen to the radio and don't know what songs are called so I could download em. I saw an advertisement for this product, and decided to try it out. Everything went well until the first time I uploaded the emarks. For some reason 3 or 4 of each song was comming up. I deleted them, but was unable to delete the emarks on my emarker. I was very dissapointed in this product, espically the software and I strongly dissuade you from buying it.
[A]:
Negative
