Review: Bought it for the 2024 eclipse, worked pretty well. It attached easily to my budget telescope and I did not go blind while staring at the sun through it, so I count it as a success.
Review: I bought 2 of them because they fit perfectly my 10x50 Bushnell binoculars. That way I can clearly see sunspots on the Sun! I firstly used it on April 8 to watch the eclipse... now, because of the strong solar activity of 2024, sunspots had been visible almost the whole year!

### ⭐⭐⭐⭐⭐ Review
*by L***S on 1 March 2024*

Works great for viewing the sun safely with my 70AZ. Seems overpriced for what you get though... just a plastic cap with the same kind of solar film as those cardboard eclipse glasses. For $25 I'd feel better if the filter was made of plastic. The film works, but it's cheap and fragile. One accidental bump and you'd likely ruin it.
