I currently have an R4, for one year exactly and it's been great. I just want to try something new and I'm wondering if there's an even better flash card out there. I want to give this one to my brother because I've been having problems with it. I have nothing against the R4, but mine seems to be defective. Almost every time I turn it on, it doesn't recognize the R4DS flash card and sends me to the main menu. Also, I've had to buy three different SD cards since they stopped working randomly. I'm looking for a flash card with the same and if possible, more features. Price is not an issue if it is a great flash card. Opinions and review are greatly appreciated.
