Very happy with these, has made my steam deck buttons feel like a more modern controller. Couple it with hall effect joysticks!You’ll need a hairdryer or heat gun

Easy install, a very noticeable upgrade, little harder to press than stock and not too loud!

Made the d-pad more responsive. I found the clicking sound a bit much for my taste so I dampened it by adding a piece of tape on top of the switches.

First, I only installed the dpad tactile button mod, which is the critical one. Not that much of a fan of ABXY button mods as no controllers afaik have clicky (tactile) buttons, but it's there if I need it.The dpad mod makes the dpad feel much better, mushiness is gone and the diagonals respond perfectly. The dpad does require more pressure to activate than before and this will take some getting used to.What is really special about this kit is what they give you. They give you a huge assortment of replacement torx screws, and a few extra springs (I believe bumper and trigger) which is a very nice touch, since it is very easy to lose a spring since if a spring hits a hard floor, it can bounce deceptively anywhere. And they even give you *two* membrane pads for each side (dpad and buttons), so you have one pad and a spare replacement. I never knew those would ever wear out but it's really nice to have an extra. You also get an extra dpad protective layer as well.Really pleased and happy with the attention to detail here, and most kits you buy only give you what you purchased and absolutely nothing else.As for longevity, we'll see. The one thing about the 'stock' capacitive layer is that those things basically last forever (until the contacts wear out, if they ever do). Note that you do have to peel off the stock capacitive layer from the original button board(s), and it's not clear whether (even if you protect the adhesive) the original can be re-used after being bent (you can see bends in the pads after removal), so it's recommended that you buy a spare button and dpad board from ifixit just in case you need something to go back to.*Edit*After seeing some of the posts here and in the extremerate subreddit, I decided to take apart my dpad section (3 months later) and checked the membrane, and the membrane looked flawless. There was no damage that I could see. Maybe the cover for the dpad has something to do with that, but I went ahead and put on another membrane that I had already applied tiny cutout squares of kapton tape to, inside of the dimples, just for good measure. I have not done the button mod at all, as I find clicky buttons a bit strange (only the menu button, which is part of the dpad set itself, is a clicker), but I can see the ABXY long button travel combining with the small hard clicky microswitches causing issues for anyone there. I am rather sure that applying kapton tape inside the button membrane dimples would help preserve the membranes-kapton tape is very resilient (it's used for high temp solder applications). But the dpad part of this kit is flawless and is a must do for anyone who hates the stock dpad. But the button section needs extra attention. Extremerate mentioned on their reddit that they were looking into a fix for this, so you can ask there for any redesigned membranes for the button section.
