Well, I only had the DSTWO for a day and already the MicroSD cards weren't clicking and sticking in place, the detent/click/spring action mount of the MicroSD card is broken. I hope the dealer replaces it and that he won't make me pay shipping to him. I broke 2 cards trying to make it work (I didn't know I broke them, long story, but MicroSDs are much more delicate than I realized. I tried using Tape and cracked them). Man I sure do hope this dealer will take care of me, and now I have to ask: Has anyone else had a problem with the method of MicroSD mounting on the DSTWO? Is this a typical problem with this cartridge and should I get another brand/model? I also noticed that I was only getting like 4 hours of battery life, and PDFs and AVIs wouldn't work on it, even with the plugin. I need some advice, which cart is the next best choice if I have to go with something else? Sadly, I don't have much money so I will have to wait a month possibly before I can get a replacement if the dealer (Real Hot Stuff) doesn't back this. Anyone know if they stand behind their sales?
