Input: Consider Input: 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.

Output: Negative


Input: Consider Input: I purchased this MP3 player as a Christmas gift for our daughter only to find out on Christmas Day that is not compatible without our computer despite every update available. While we could see the preloaded video and it is very clear and bright, we were never able to upload any music. My husband (who is computer wizard) spent 12 hours trying to get this thing to work, but without any success. Next time we'll buy an IPod.

Output: Negative


Input: Consider Input: This set of assorted short tracks is hard to avoid if you want to create a track layout of even an intermidiate size. The male-male and female-female pieces will provide a dramatic increase in the number of layouts possible as you can now overcome the problem of curves returning to the starting position.This is a must-have for any Brio enthusiast.


Output: Positive
