I am at stay at home mom and sell on Ebay to get rid of the clothes my kids have outgrown. This is not a career for me, just looking to make a little money by selling my kids outgrown, gently used clothing. I work hard for A+ customer service!
Both of my kids (ages 4 and 9) each have a DS. They love to do battles and write back and forth to each other, so the wireless feature is a huge plus - they can both easily play the games and I love the fact that it plays both DS games as well as Gameboy games - more options that way!
On to the negatives - I think that the hinge that holds the upper and lower portions together is cheap - though they have not personally broke theirs, you can really hear them when you open and shut them and they just feel like they are cheap - not very sturdy. Also, the stylus pen is great because you need it for some games, but it should have some sort of feature where you can attach it to the DS so it can't be lost (even though you can buy them separately and they are pretty cheap, it is still annoying!) Also, though we have not personally had any problems with them - the screens - a lot of people seem to break and or scratch them - I know you can purchase protectors separately but why not have them come with the DS if it is common enough of a problem that you have to make them to begin with!
Even with the little flaws - if my kids' stopped working, I probably would buy them another one - they really like them and I like all of the color options - they both have a different color and I just bought one for my mom for Christmas (so she will stop taking theirs) in a different color yet - so that way at a glance we know whos is whos and there is not fighting!
