I find it really odd that they require a third party to look the heads over to maintain warranty.
You could bring them to some shop known for poor/shoddy work, they find several things they don’t like, and “fix”(****) them up for you.
Then you have a problem cuz the shop fucked them up....... and SM is now gonna take care of you?
Mmmmmm, I don’t think so Tim.
