The adhesive is strong and the two shapes allows for options in mounting

The adhesive is not strong enough

The attract really well to many different types of magnetic phone holders, and have strong 3M adhesive.

The adhesive is ridiculously weak, you'll be lucky if you can get them to adhere to your phone case

Not much to rate here, they donthe job, they have a nice flat adhesive backing and a clean look

The adhesive is decent.

works fine, good adhesive.

the adhesive on them wasn't so good

These are the right size and have good adhesive

They're cheap, flat pieces of metal, with good adhesive

The magnet lasts pretty much indefinitely, but if you get a new phone, or a new case, you can quickly run out of the metal plates since they stick to your phone case with a pretty strong adhesive and don't remove very easily

They have a strong adhesive that keeps them securely attached.

Great quality and adhesive will stick to anything.

The strength of the magnet is very good though, just not the adhesive

These are what they are, and the work very well -- good quality adhesive to attach to your device

The adhesive on these is strong

These are kind of deceiving as they are not magnetically charged

Works as it should.
