I have a jewelers loop 30x 60x and then a magnifying glass, i just bought another one that does 50x-1000x that was supposed to work on a cell phone but When I bought it, it didn’t come with the right piece to hook up to my phone so I had to buy another one and then when I tried using it, it said it was taking up too much power for my phone and so it wasn’t gonna let it work. Hooked it up to my laptop to use it in the picture quality just wasn’t what I was expecting and was not worth what I paid for it so I’m returning it
