Great product
Size: 4 Fl Oz (Pack of 1)
Used this stabil in my rider after first start of the season. Machine running rough and uneven. Drained old fuel and added it. Within 15 minutes at full throttle it began to run normal. No back fires and engine back to normal. There will always be a bottle of this in my garage.

Works Great
Size: 8 Fl Oz (Pack of 1)
I"ve used Stabil gas treaments for year but never this particular type. With gas the way it is, I decided to see how it might help my mower and also my older truck. My older push mower which admittedly doesn't get pampered and petted seems to love it. Either it's grateful to get anything special or this stuff really has helped. The first tank seemed a little smoother but by the second I could hear the difference and feel it with the smoother sound and seems more power. It's easy to mix and use and Stabil is a well known reputable company.

Easy and worked seamlessly with the new Apple MacBook Pro
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
This was our first (Apple MacBook Pro M4) and big purchase directly on Amazon. I was not concerned about the order and product, but more concerned about the AppleCare+ not being connected directly to the device (after reading some reviews). However, I am happy to report that this was the first thing I checked as soon as we set up our computer. We are set for 3 years ... so thank you, Amazon and Apple, for working out the backend stuff and making our lives easier. It worked for us. It was easy, and I am happy with the overall quality of the process. Oh, don't forget it was cheaper than buying yearly from Apple directly.

Don't buy AppleCare from Amazon, won't "attach" to your device automatically
Style Name: MacBook Pro 14" (M4), Configuration: 3 years
As another reviewer said, Amazon should not be allowed to sell digital items like these and fail to deliver them. That's called a scam. I have yet to receive my AppleCare agreement, but Amazon was more than glad to charge my Amex right away.
Purchasing AppleCare from Amazon will only get you to a download of a PDF of the general terms and conditions, from your "Software Library", but it is not YOUR actual user agreement, and will not register on your device.
Amazon will not help either, they will refer you to Apple support, and Apple will tell you that without an Agreement Number, they can't apply your AppleCare to your device. Since the PDF Amazon directs you to is a simple General Terms and Conditions document, there is no Agreement Number. In addition, the purchase invoice doesn't show this Agreement Number nor the device's Serial Number (which Amazon claims is recorded with the purchase... it's not)
Save yourself the headache, and buy AppleCare direct from Apple, it will be about $60 more, but the "savings" is not worth dealing with this Amazon stuff. Amazon will also refuse to process a refund, stating that "only Apple can do that". Guess Amazon is telling you to contact your credit card and initiate a chargeback for services not received as paid.

Was skeptical but it worked out of the box
Style Name: MacBook Air 13" (M4), Configuration: 3 years, Style Name: MacBook Air 13" (M4), Configuration: 3 years
Was skeptical at first but decided to pull the plug and get the m4 laptop with 3 years of apple care and it works. Haven't even opened an email or anything, laptop was still fresh out of the box. When I remembered I bought apple care and decided to check. Applied instantly as far as I know once I linked my apple account on the first boot up with internet! Good stuff
