I have been a PC and Laptop Repair tech since 1999, and Got my A+ Cert in 2001.
I worked in a Tech Shop for 5 yrs, moved on to a Local onsite repair. And since Oct. 2009 I have been doing PC Phone support from home.
My hobbies are gaming, messing with all aspects of computers, and I started repairing Game Consoles back in 2011 when I realized it cheaper to collect broken systems and fix them than it is to buy working ones.
Used this on both the Left and Right Joycon, the Left Joycon has an extra ribbon that goes over the analog stick. So yes if you dont have to take off the 2 ribbons that connect the 2 halves don’t. Great job!
