Works as described!

I wasn't getting cramping hands when holding the ds like some others, but this just makes it more comfortable

it's a good size, feels really sturdy, and makes my 3ds far more comfortable for my giant hands c:i DID have one problem, however: while the handgrip uses a large plastic strip along the top of the console to hold it in place, there's only a teeny-tiny plastic tab holding the bottom part of the console (it's below the d-pad)
