MSI BGP100 Bluetooth Gamepad (1*AAA Battery Included)

Pros: Very responsive and fast which is a must for certain games.
Long battery life with just one AAA battery.
Supports all Windows Mobile 5 & 6 phones as well as others.
Good build quality
Can also connect to your computer.

Cons: None, Although a build in rechargeable battery would be nice but asking too much =)

Other: Get this gamepad if you have a Windows Mobile phone, You can install so many great games.

Pros: -Good weight.
-It feels comfortable in your hands
-it work in Windows XP and even Palm
i love the package with it cames XD

Cons: -Drain too fast the battery of the gamepad.
-i really think that if the gamepad drop for a one meter it brokes

Other: I think the slowy its for my device , because the Qualcomm processor much have better perfomance than the Xscale.

Pros: This thing hooks up to my Nexus One with the GamePro App! Thats awesome. I can play emulators on my phone without having to use the touchscreen. Battery life seems pretty good.

Cons: The build quality is not very good. The buttons have a crappy cheap feel to them. The whole unit itself feels like I could easily snap it to pieces with my hands if I tried.
Wish it had a "Select" button so I could completely map a SNES controller.

Other: This works if its your only option for a gamepad. It DOES work, and it isn't difficult to use. The problem is it just feels very cheap, and it makes me wonder how long its going to work before it fails.

Pros: Almost universal gamepad
Relatevely good built
Nice price compared to similar offers

Cons: The design only fits for games played in portrait mode
The buttons and d-pad have that annoying clicky feel
The software isnt upgraded since a long, you depend on third party developers

Other: For the price i recommend it to everyone who like to play emulators on his smartphone, but you have to find proper working drivers, as the official ones are non-existent.
