For the price it gives very good results; I have been able to see some details of the moon with my little F8 Ultra and this x18 lens.
I loved the monocular lens; it took a long time to arrive, but everything arrived in good condition. The lens is perfect for taking long-zoom photos, but a phone with a good camera helps too. I took some photos and loved them, and of course, I took a photo of our beautiful Moon.
Very good product, has perfect zoom and focus. The only thing I recommend is buying it with a tripod, our hands shake a lot haha. But it's perfect!!
Very good, works very well.
It's good to use a tripod to keep the image stable.
The material is good.
I posted two photos comparing the zoom of the cellphone with the zoom of the lens.
