[EX Q]: This is one for the hard core action fans. There's very little 'down time' to run for popcorn. If someone isn't getting shot, punched, etc. things are getting blown up or sunk in water. There is an action scene I haven't seen yet with a police car. Several of the action scenes are worth a rewind and I did appreciate the 'buff bodies'. You have to give these guys an A plus for working out.Chrissy K. McVay - Author

[EX 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.
[EX A]: Negative

[EX Q]: This rattle is easy to hold and has an added advantage of being able to roll around the floor. This makes my grandson want to crawl after it. It's well made, makes a nice rattling sound. I would buy it again for my grandson as it is quite nice. He didn't show interest in it until about 7 months and now that he is one plays with it a bit. The only negative comment I have is that he loses interest in it after a very short time.
