Pros: Cheap, its Genuine and works with the new 32GB SDHCs. I've got about 1300 roms on mine and it's never failed.

Cons: None. Except the 500 character minimum. Damn that minimum.

Bottomline: The box was squashed so that it could be shipped as a letter.

Pros: I have been buying these for a few months. They are genuine R4i flash carts and all have worked on the dsi without a problem.
They meet the genuine criteria and don't appear to be clones but most R4 came from the same factory. They have been consistent in build quality and fit well into the slot 1. All games have loaded with the 1.54 firmware downloaded from website.

Cons: No cons for this product, as stated before all cards have worked with the 4 gig micro sd cards in the ds lite and the new dsi with the 1.54 firmware.

Other Thoughts:

Bottomline: Worth buying this device to play all homebrew and game roms.

Pros: No real pros for now because i still haven't managed to make it work on my DSi.

Cons: It seems to me that this is not a R4i but just a normal R4 ultra, i tried all the firmwares i could find for R4i but they didn't work. I don't have any ds lite or ds to try it on, so i guess i'll just have to wait and see if i can still use it on a classic ds lite.

Other Thoughts: The package was a little crushed when i received it. It's pretty bad if you want to resell it.

Bottomline: I thought i would work on my DSi but obviously it's a fake, with just a R4i sticker on it (awful job on applying the sticker by the way). I bought the other version (the red one) to see if it works. If it doesn't, i'll give up and try another brand.
