Pros: All the speed I need. Scan's look good. It's duplex too. You're really buying two scanners which stack on top of each other. The software from Canon's website is very effective.

Cons: It skews smaller receipts sometimes. Software corrects it very well. It scans faster than I can sort and load. The software built into the scanner is so buggy.

Overall Review: With the built in portable software, my C: drive filled up while processing a big job, lost the entire job cause it errored, had to redo from scratch. I closed the scanner, lost the entire job cause it errored, had to redo from scratch. Do yourself a favor and instead use updated software from Canon's website, it is flawless now.

Pros: Does visuals well, interface is decent enough, I don't see any rainbow effects, durable.

Cons: The audio from HDMI input clips, causing all kinds of audio distortion on the internal speaker and the audio-out. The only resolution is to bypass the audio and run it from a separate amplifier or receiver.

Pros: XV-21 looks new and works like new. Good suction. Floor is surprisingly cleaner. The dust cup is one of the easiest I've ever had to empty.

Cons: XV-21 has trouble getting back to its base station on the battery power it reserves for that purpose. I find that I don't mind giving it a lift from time to time after how well it performs.

Overall Review: Its loud like a smaller upright stick vacuum, I can still hold a conversation in the same room, but its not enjoyable to do so. The cat is indifferent to it.

Pros: They look good on the desk. Easily accessable plugs. They can get decently loud. Great for video games.

Cons: The speaker housing is very thin and they sound boomy and plasticy because of it. Bad resonations from the body of the speakers. This is one of those products designed by a talented team and then butchered by sales afterwards.

Overall Review: These do not have the wonderful sound of their old line of speakers, such as the FP2000 from years ago. Those cubes were superior in all regards. The unmodified T40's are bad sounding enough that I was compelled to write a review to tell others to go buy something nice instead.

Received my product, thank you.
