NO!!!
Jesus Christ DO NOT GET AN R4!!!
Trust me, I used to do reviews, R4's are the worst pieces of shits ever, get the CycloDS, its the best flashcard on the market.
Do ever buy an R4 for $50 or even $25, YOU ARE GETTING RIPPED OFF!
They go for about $8 now, they are cheap as hell because they suck.
If you don't want to spend a lot of money on a flashcard go with the AceKard 2.1, its probably the best valued one. However, CycloDS is the best on on the Market.
BUT DO NOT GET AN R4
