Good Mount / Poorly Connected Magnet
Good product. It fits well on my Model Y screen. It worked fine for 3 months. but then the magnet became loose from the ring. I like the product so instead of discarding it thought of using glue to stick the magnet back to the ring. BUT it didn’t work. So now it has been a frustrating experience. I may choose to discard a product that has a strong mount, but the one important part (magnet) not working correctly.

Cleans with no streaking.
I made my own cleaner and these cloths work great! Im so happy that I got these, no streaks, the glass is clear and cleans them faster. Worth the money.

Secret to Great Auto Glass
Awesome product. I struggled with getting clean streak free glass on my truck. Thought it was the cleaners (multiple). It was the cleaning towel. This one rocks! I've bought 4.
