New Apple AirTag
New Apple AirTag compatible with iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max. Testing conducted by Apple in March 2021 using preproduction Air Tag units and software paired with iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max units running preproduction software.
Battery life based on everyday use of four play sound events and one Precision Finding event per day. Battery life varies with usage, environmental conditions, replacement battery manufacturer, and many other factors; actual results will vary.

Air Tag is splash, water, and dust resistant and was tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529 (maximum depth of 1 meter up to 30 minutes).
Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Refer to the Safety and Handling documentation for cleaning and drying instructions.

You have been waiting all year for Apple to release this and you can have bought the 4 pack one. You can use your car key, house keys, and more. This is amazing as they are so small that they can fit practically anywhere.

No weight issues whatsoever. There will be no problems with this on keys, bags, etc.
A simple compact design that doesn’t draw attention.
Setup took seconds to get ready as the software is already on the current IOS.
Waterproof with an IP67 rating. This means it can take the rain or even if it’s dropped in a deep puddle. Overall, it can hold against Mother Nature.
Battery replacement is quick and painless.
Thank you, Apple for not making your own expensive battery for this. The battery inside is a CR2032. These usually last one year and are super cheap to get. You can find them at the checkout lines of a grocery store such as Walmart (and of course Amazon).
