My only recent "complex" task that needed their tools was adding a hybrid water cooler to a 1080ti GPU. Their stuff was great, and their customer service has been good too. (EDIT: I meant to say, the addition went well due to their tools, good quality stuff means easier job with tiny screws)
I'd love to see the right to repair/replace be enshrined in law. It's possible to strike a balance between tiny components and being able to replace them. My phone, a LG V20, is very thin, yet has a replaceable battery and is still waterproof to a "certain extent" (MIL-STD-810G but I'm not sure what exactly that means for waterproof-ness). Which is kind of amusing because I dropped the damn thing in the sink for the first time ever this morning.
I'd love to see something like T-Mobile partner with iFixit and certify particular phones to be user or expert repairable.
Hopefully this is the start of a larger movement in the world.
(EDIT2: I really didn't intend this comment to sound so public-relation-y. I swear I'm not a product placement shill!)
