question:
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.
answer:
Negative


question:
This product arrived on time and in excellent condition. These boots have a good arch and seem sturdy. They do look a little cheaper than I anticipated. The tread is great. Size runs true.
answer:
Positive


question:
I filled it with air when it arrived. It lost air by the morning. Since the bed was cold when filled, I gave it another chance. The first night is was actually used, it had to be refilled in the middle of the night.
answer:

Negative
