I know it's easy to make fun of this product, but genuinely these cloths are made of exceedingly premium materials that will clean and protect your precious devices. Other cloths literally fall part the moment you use them, scratching up your screens and leaving dangerous residues on the surface. Paying $19 to avoid this catastrophe is well worth the money.
Most of us spend thousands of dollars on Apple devices every year. Is dropping $100 on a few exceedingly premium cleaning cloths really a bad investment to protect those devices?
I certainly wouldn't trust me $4000 MacBook Pro with some $1 cloth i found on Amazon. Nor my iPhone. Nor my iPad. Nor my Apple Watch. I only use Apple Cloth now and I am absolutely satisfied with the seamless experience across all my devices.
Spoken as if you never before used a cleaning cloth.
