1 It's very unlikely you'll be able to open the controller without breaking the latches. I wouldn't recommend getting them unless you need to open them for some other reason.2. I have a DualShock 4 CUH-ZCT2, it wasn't clear these buttons are for the DualShock 4 CUH-ZCT1 models. Specifically, this means the options/share buttons are 100% unusable, but I can't say for sure if the other unusable buttons are manufacturing issues or model issues.3. Buttons not used: options/share (wrong model), triggers (missing button click bar), joysticks (slot depth is wrong so redirect subs get caught on the insides when you move them, although I think you could stick something in there too to fix that) , touchpad (the original comes with touch hardware, so the average person can either not use this crisp pad or use it without touch support, which some games require)4. From matching buttons they had to be filed, all had labels from the bar that stick and we have slightly larger than the original. For the front buttons you can remove the tabs but for the bumpers you will need to remove the tabs and file the 4 guide teeth as they cause too much friction. In general the quality is not very good, half was not usable, the other half was usable only after filing, and I definitely broke some of the plastic in the controller, but I still had to open it up for another repair.
