Currently still using them for a Wii U pro controller, and an Xbox360 controller. Will definitely be buying them again for extra controllers, so I highly recommend.

Short and Sweet. These are great on a PS4 controller as long as the original cover is still in tact. If not then the cover comes down to far and impedes the movement of the joysticks.

Fits on WiiU and PS4 controllers just fine, snug fit. Keeps falling off XB1 controllers, too loose. Still well worth the price.

These work very well on my Rock Candy, wired controller, which did not have rubberized stick tops.  They fit snuggly on top, hold well, do not slip around, and give me considerably better control.  Comes four in a pack.  It even want well with the red color of the controller.  They should fit any other Xbox controller as well.

These panels seem to fit great! But they are just slightly off color compared to the standard Nintendo Wii Remotes. Really only noticeable if you stare at the remote for a few seconds, but when it's in your hand and you're playing a game, who cares. It keeps the batteries in place perfectly, and that's what I needed!

I bought these along with a Hard Drive for my Wii U and they work flawlessly.  I am very happy with my purchase and would recommend for anyone needing this for their Wii U or other consoles they might have.

You'll need to be comfortable with taking things apart and reassembling them (take pictures as you go or find a YouTube guide) These things are great. I have an old 360 controller I now use for my PC/SteamLink. The rubber on the thumbsticks was worn down to the plastic in some spots, and missing in others (post bird-attack) plus there was dust and sticky buildup at the sticks and on some of the buttons. The thumbsticks themselves were a perfect fit and replacment and are comfortable to use, including extended sessions. As an added bonus, i was able to clean all the plastic parts, essentially restoring the controller to the condition it was in when it was new. The fact that it comes with the required screwdriver is awesome and means I can clean the rest of my controllers if needed, plus I have extra thumbsticks now if I ever need them as well.

The analog sticks were a perfect fit, and have been working as a great replacement for the original sticks. The D-pad was chrome-plated plastic, not metal, despite the product description. No big deal, since I was only replacing the analog sticks anyway. If I ever wear out the original D-pad, the one in this kit would make a very nice replacement.

Saw these and had too order them for my controllers. They are excellent quality, with almost a suede lining on the inside to protect from scratches. Mine do not have the issue with the thumbsticks being pushed down when closed, not a big deal anyway.

It looks and feels great!! Sticks are slippery wich don't bother me cuz i got grip its for them wich are the best stick covers i have ever seen!!! There only 4.99 on this site! So get them if your gonna get this controller. The presition aim i don't really use cuz i don't snipe. I set one of them up for an extra reload button! Dont be madd that its a wired controller,wired controllers are better for first person shooters since they give u a split second advantage on everyone else. There is a split second delay with the wireless controllers..So this controller will give u a little leg up on everyone else if u get use to it!!!

I bought these because some of the buttons on my XBox controller had been sticking.  These worked perfectly.  The bolts on the controller are seated in deep holes, so the longer bits are a must.

Great covers for my controllers. Adds a nice look to them and has protected them after a few drops. The only downside is that you can't connect a regular Xbox One mic to it without screwing with it.

These do what they say they do.  They snap on the PS4 control sticks and give you more "Control".  I ordered a pretty good sampling because I wasn't sure if I wanted concave or convex and/or what height.  This is a personal decision so I cannot really recommend any particular style.  It really depends on your game play.  I use a taller stick on the right for FPS games, swap a taller stick on the left for driving games.  Great little product.  I'm sure I'll buy more.

I highly recommend this product! If you are into product reviews and Unboxing I actually did my own on my youtube channel.
This controller feels very light and the buttons have a ton of feedback, clicky buttons. The quality feels similar to the Nintendo Gamecube Smash Controllers that came out recently, isn't as heavy as the older original GC controllers.

I primarily use this as a controller for Smash Bros, however, it works on all Wii U and Wii games that support the classic controller and Wii mote setup. SUPER GOOD BUY FOR THE PRICE!!!

Excellent controller with great battery life and the best analog sticks on any gamepad. Shoulder buttons are a bit cumbersome.  4/5

These work just as you would expect them to. The shape and size is just the same as the sticks that come with official Xbox One controllers.
These also fit perfectly into Wii U Pro controllers (probably the gamepad as well). I've been playing ranked matches in Smash Bros and it's much more pleasant than with my old worn out rubber sticks. I also prefer concave to convex, so that was a big reason for me to switch. As corny as it sounds, it did improve my game slightly.

The metal is nice. They feel only a tad heavier than plastic/rubber sticks. You can kinda feel the weight when you're knocking it around. Some people might like that, just as some additional tactile feedback. I do, personally. The center is very smooth and the outer rim has ridges which gives grip. You may find the smoothness to be slippery, but I don't find this to be a problem. Since it's concave and has a small head, my thumbs aren't slipping around. Also it doesn't chafe my thumb after long gaming sessions like the rough rubber ones sometimes do.
I may replace all my sticks with metal ones. Or at least some of them.
