@nweberstorm They both have different features really, the lycosa is a much smaller and slimmer keyboard too. If you ever think that you would like to use one of the keysets or make use of the seperate macro keys this one is for you, but both are very solid picks :)
@cjere2k9 I don't remember a black plastic thing in the box..is it to do with the clamping system? If you are stuck maybe send us a picture to support :) or maybe you got lucky and they sent you some freebies? :)
@MasterSocer There is enough room in the case to support the silicone cover on top of the 3DS :)
