I had a series pad 2 and like everyone love it to bits, just recently started to get a horrific drift on the left stick, came across this site and never knew anything about it. Ordered and when arrived was impressed by the quality and the packaging.
The series 2nis easy to open and thanks to the image was able to solder in less than 5 minutes (always use flux so you dont damage anything when soldering)
1 annoying thing i did find though is when you are on the website you cant adjust on the fly as everytime you pull the pcb to adjust the pots it powers off the pad. Not a problem though adjust a tiny bit at a time, take screenshots so you can see what you are changing. Ten minutes later the pads like brand new. Thanks zedlabz amazing product will recommend to everyone and will use in future
