Didn’t replace my speakers but had to remove them to clean the speaker grill area due to debris. This was a good spill as it allowed me the opportunity to nearly disassemble and gain a better understanding and appreciation of my beloved Macbook. I’ve never been inside a Macbook and from a technicians’ viewpoint I found the guide(s) here to be excellent, specific task assistants. It’s good knowing the machine is lint, dust, and pet hair free, cooler, with better thermal paste, and threw in a new battery while the egg was cracked. Sincere thanks to you folks at iFixit for doing such a great job. On that note, I had purchased a battery on ebay at a slight savings over your own and I regret this. Had I known I would have been relying so heavily upon your efforts I would have certainly made my purchase from you. The future will find me correcting that error. I imagine your parts are every bit as good as your advice. Thanks again!
