DSTT is by far the easiest card to use for beginners. Its high compatibility with NDS ROMS is comparable to R4 or may even surpass it. It also features 100% download play as well as link play, and don't forget the wi-fi connection play. Compared to DSone, DSTT has proven to be more powerful in terms of gaming (DSone has moonshell within its firmware), and link play. It can be said that DSTT should be the new generation of R4.
However, it does have its down side. The Failure rate of the card is significant. About 3/100 cards failed to be read, and 2/100 cards may stuckin loading screen forever; I concluded that the failure rate of the card is about 5%.
Another thing that should be noticed is the awkward situation where DSTT fails to create a SAV. File. This is not of major concern as it is not the hardware failure, but software failure. If this happens, simply put the NDS ROMS into many different folders; each folder should contain about 10 NDS Roms. Reason behind this is due to the limit of files restricted in one folder for the DSTT, I believe it is limited up to only 50 files, and after 50 files in one folder, DSTT has a high chance to fail creating a SAV. File.
How to Improve?
Manufacturers should treat their products more seriously, I've found some of the DSTT to be dirty and those ones break very easily.
Handlers should not tie 10 DSTTs at once or put them together too tight with an elastic band, as it will bend the DSTT card and sometimes lead to failures.
Broken ones should have warranty and insurance policy with it, as the rate is high; this way will support long term customers as well as one time consumer.
In the end, I believe it is safe to say that consumer benefits most out of DSTT compared to R4 and others, as I highly recommended it.
Verdict 9/10 (10/10 if the failure rate is between 99%~100%)
