Pros: Extends battery life. Centers itself nicely in the charge base.

Cons: Overkill on the charge base LED's. Not sure how I feel about the copper charge pads being in the center of the backside, not set in by very much.

Overall Review: Rubberized coating smells funny for a few days. I found myself washing hands after every use. The extra thickness doesn't really bother me. Also, unless you want this thing to double as a night light, you'll want to perform a simple mod involving black electrical tape. Cover both of the LED strips on the slanted bottom/sides, and cover most of the strip on the top side, leaving just a small square in the middle to indicate charging/charged. Otherwise, this thing puts out as many lumens than your average flashlight.

Pros: Its far better than the default controller for fighting games such as SSF4, given the 6-button layout. The cord is plenty long and you don't need to worry about batteries. Also, far cheaper than one of the Pro/Arcade type controllers.

Cons: I RMA'ed the first unit, but the second one has the same annoying random control inputs that the first one had. It appears to be a slight nudge to the left, either in the analog stick or D-pad, but tapping or wiggling either of them does not replicate the issue, it is truly random. Outside of the obvious issues this might cause in timing-sensitive games, the thing that truly bothers me is that if the controller is left plugged in while watching a DVD, the menu keeps randomly popping up and you have to hit B to close it. If you leave it open, the menu selection will sometimes change. I'd really hoped that this controller could just be left plugged in at all times so I wouldn't have to keep powering up and down the regular controller to control the DVD, but I ended up leaving it unplugged for this reason alone, its HIGHLY annoying.

Overall Review: I never really played with the Turbo functionality so I can't comment on it. Overall, its a decent enough controller and I still use it for much of my gaming, but given the random input issue, I can't give it more than 3 eggs. Maybe I just got two bad ones in a row, but I don't feel like waiting for another RMA, or paying for shipping again to do so.

Pros: Didn't have any problem installing drivers or getting XP Pro to recognize it.

Cons: The <expletive>ing thing simply doesn't work! I plugged a crossover cable between the two serial ports, opened two terminals, and whatever I typed into one terminal would come out the other. Great! Connecting the card to the device I needed to talk to didn't work. Uh oh. I took the crossover cable and connected one of the ports to a serial port on a different computer and no matter what settings or configurations I'd set, whatever I'd type into one terminal would only spew gibberish into the other. I've never seen this issue before, nor have I been able to fix it.

Overall Review: Its a piece of junk with no useful documentation, no support whatsoever, and some sort of weird proprietary communication protocol that only *it* understands! I've never really had any luck with add-in serial cards and shouldn't have bought this one. From now on, I'm sticking to the USB squid types - at least they work most of the time.
