Yes, of course, you can purchase a second-hand gaming device, whichever it is. The important thing here is like most electronics, it isn’t possible to detect any faults until you start playing it. To avoid this factor, make sure you ask for a trial run at the seller’s place or loan it for a day to test it out. After trying out a couple of games on it, you can then make your decision. Also, make sure you strike a good bargain.
