LeFix 3 x Super Low Profile Trackpoint Caps for Lenovo Thinkpad T460S T460P T470S T480s T490s E580 E590 X1 Carbon 4th 5th 6th Gen (Compatibility on The Description Page)

Bought this to replace the default rubber c-stick nub on a New 3DS XL.The rubber nub wasn't particularly accurate, what with random amounts of force needed to change direction and it itself getting moist and slippery, requiring even more pressure and thus less precision over time(15 minutes?)After having it yanked out slowly with a pair of tweezers, the red Lenovo cap fit *PERFECTLY* - no wobble at all, sitting tight and doesn't reach the top screen in the closed 3ds position.Accuracy immediately bumped up considerably, as the cap stays in place, doesn't move, doesn't fold, doesn't squish, and only light pressure from the finger on it perfectly controls in all directions. After getting used to the changed sensitivity for about 10 minutes, it's pretty much the perfect replacement imo.PSP 1000 'analog" stick also fits, but it wobbles back and forth cause it doesn't actually totally fit - this one is solid as a rock. 100% recommend.

3rd party supplier had a great ad that guided me to purchase the correct part.

I had ordered a set of these previously, for my laptop. The description had my model, but the square on the back was too large. Someone had posted an alternative and this description had my model, BUT, and this is important, this one had the dimensions - diameter, depth and most important of all, the dimension of the square that fits over the keyboard 'button'. I am so happy and am so impressed with the responsiveness of the puck!

Fit the model listed, much needed replacement for any worn out track point

If you are purchasing for a Lenovo thinkpad T470 don't bother they don't fit. It's like a cartoon character forcing a shoe on it just flies off in another direction.
