John - VERY nice and helpful video. I wish I’d had the iSesamo opening tool that you used. I got it open but dinged the case a bit with the larger tools that were in my iFixit tool kit.
It also took longer than I’d hoped but I was successful at it. Also, where can one purchase the double-sided adhesive to keep the new battery down?
I’m very pleased with the result of the battery replacement and once again, your video was terrific. I had it on a 27” Cinema display right on the table where I did the work.
