I read a lot of comments that said there was an issue with their purchase of AppleCare+, I did not have any of those experiences. AppleCare+ was on the laptop (MacBook Air, 13-inch 2025) automatically. I received an email with my confirmation of AppleCare+ coverage, along with my agreement number, product serial number and expiration date. There was nothing I needed to do on my end, because as I said it had already been added to my computer and attached to my iCloud account. — I hate that there are so many bad experiences and hope everything works out for anyone experiencing a nightmare but I can only recommend based on my experience, 10/10.

Fantastic product

Size: 8 Fl Oz (Pack of 1)

Works Great, at first didn't believe all the reviews, I've bought 5 chainsaws from one season to the next. After each winter couldn't get them to start. Followed the instructions to flush and let sit for a few days. Every one started and ran great. Hands down, this is a remarkable product for cleaning out blocked fuel systems from sitting all winter would recommend it for all 2 cycle engines and use the stable blend for winter as well as anytime use to prevent fuel spoilage.

Efird, a great product

Used this in a Troy Built Garden Tiller, the tiller would stall and hard to crank until we use the Sta Bil Fast Fix, tiller now runs great and does not stall.

Worked great, saved me hundreds.

Size: 8 Fl Oz (Pack of 1)

I've had issues with the carburetor on my 2003 Honda ATV for years. It has needed cleaned regularly to stay running, and one repair shop wanted over $400 to replace the carburetor. One treatment with STA-BIL and it's running smooth again. Very impressive.
