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: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.

A: Positive

Q: I have one of those "spare tire" waists, but when I put this on, I had an hourglass shape... I've never had results like this with any other shapewear... But it does come with some side effects...Wore it to work for 8 hours, took it off to find that my skin was a grayish color (i'm black) and had lines (which turned to bruises) on my sides and lower back where it folded from sitting... I did like the way it gave me a much trimmer waistline, so the next day I wore a camisole under it and it was very comfortable. That experience did, however, give me more incentive to exercise and get fit so I don't have to depend on anything to "make" me look trimmer...

Positive
