Works for the ORIGINAL Ninendo DS

After years of playing my old Nintendo DS, it's battery could no longer hold a charge. The battery was an exact fit and charged up rather quickly. When I turned my DS on, everything seemed normal. Finally I can play my DS without being plugged into an outlet for once. Saved me from buying another DS and from spending a lot of money!

Gave to niece as a Christmas gift for her Nintendo DS and did not fit/ was not compatible. Not sure what the heck I was sent as it specifically states that this charger should work for the original Nintendo DS which is what she has.

It's just a charging cable but it works great. If your original Nintendo DS power supply doesn't work anymore, this makes a pretty cheap replacement.

It works great! I was so excited, we have an old DS and couldn't find the charger for it. Local stores wanted over $30 for a charger, so I found this one. It works great!

I bought this for our regular Nintendo DS since ours was missing and it works perfect. It is the same color has the one for the regular unit.

I'm giving this 4 stars because my N64 didn't always detect it at first, but that may have been a fluke as it seems to be working consistently now. I also am a little unhappy with the color  it's a slightly darker, greener gray than matches the rest of your N64 stuff, but chances are this is probably the memory card/controller pak you want for your N64. See, these things have batteries in them and they work just like the 256k SRAM in Game Boy games, albeit with a bigger battery due to larger space. What that means is that a 20 year old controller pak might not save anymore because its 20 year old battery is likely dead, whereas to the best of my knowledge these are brand new, with brand new batteries. In short, I'm not positive this is quite as reliable as a Nintendo brand Controller Pak was back in 1997, but I *am* positive it's more reliable than a 1997 Nintendo brand Controller Pak would be in 2016. And although the color doesn't match, if you have a dead Controller Pak and a "Gamebit" screwdriver it should be a cinch to swap the board.

Awesome price and very durable. Works perfectly for original ds games and ads games. I will definitely buy another one of these if we fill this storage case up and need to get another one.

This review applies to the original Cosmo Black Nintendo 3DS console.
My rubber Circle Pad became worn out  through intensive gameplay sessions  (my 8 year old brother in law plays aggressively) and eventually came off. So once I received the Circle Pad covers, I chose and applied the GameCube themed cover and closed the system. It fits very well but I see how it can come off during gameplay so I carefully applied a tiny dab of superglue between the naked circle pad and cover replacement.  I can confidently say that it will safely close 95% of the way. I carried it around in an executive case that carries two cartridges and put it in a side jeans pocket for an entire day and there is no signs of immediate damage. The only con I can report is that, as another reviewer mentioned, is that gameplay does feel a bit sluggish during gameplay. It's minor however, and beats a loose or naked circle pad any day. I hope this helps anyone in need of reference.

This is a great substitute to the analog stick that came with the original controllers.  Designed like a Gamecube analog stick, this replacement eliminates the durability issue that exists with the N64 stick, which could be worn down from aggressive maneuvers many games demanded (such as the Bowser battles in Super Mario 64).  The replacement does have increased sensitivity and will take some getting used to for those familiar with the original analog stick, but it's only a minor drawback that can be overcome with some practice.

Installing the replacement is a fairly simple, 5-10 minute procedure of opening the controller casing (be careful with the buttons, which will fall out), unplugging the original stick, and plugging in the new one (the connector is a little snug, but will fit).  Packaging directions with the replacement would have been a big help in any case though.  Make sure you have a precision screwdriver handy...great opportunity to clean the casing and buttons too, if needed.

This is a great solution for missing thumb-pads on Playstation Portables (1000 - 3000 series).  It basically just snaps right on, and feels and performs like the original one.  Very happy with it!

Worked just fine for the Nintendo DS. Great price for a game console we dug out of storage.

a few days before I wrote a not so good review about this item, but actually is prety good, work fine it's a little too sensitive, but is good enough to play the old school N64 games and enjoy it as much as in the old days.

in my last review my main complaint was that this itam was suposed to be a original nintendo brand product, but after carefully checking back the seller description i noted that actually the seller states that this is NOT a nintendo brand replacement joystick

Both of my kids lost their original stylus pens for their Nintendo 3DS (XL).  These replacements work great with the 3DS.  But be warned, only 2 of the pens included in the pack will actually fit in the stylus holder slot in the 3DS.  The others are too thick.  But that wasn't a big deal for us, since they just keep the extra ones in their carrying cases.

Works well with my gamecube, a great replacement for my old controller

My 3DS XL has a broken charging port, so I got this and it works. It is a bit difficult to get 3DS XL lined up perfectly to make contact and actually charge, but that is a small price to pay to be able to charge my 3DS again.

My charger port broke years ago but then I bought this. This lets my 3ds have charge for days. It came a few days early and came with the small screwdriver and screws.

Bought this for my Nintendo Switch, and works perfectly with my old Original GameCube controllers. Tested on Mario Odyssey and Mario Kart
