Review on High Powered Monocular Telescope for Adults - 12X50, Waterproof, BAK4 Prism, 🔭 Ideal for Bird Watching, Wildlife, Camping, and Scenery - Use with Smartphone, by Relybo by Michael Domus

This is a very simple telescope that allows you to really zoom in without losing quality. The telescope itself looks pretty well built, encased in a rubber case that feels pretty solid. On the other hand, there is not so much for the assembly of the mobile phone. Regardless, the stand does the job. Note, however, that you will need to support the camera with your hand or the included tripod to keep it centered on your phone's camera lens. Other than that, there's nothing else to complain about, it definitely allows you to take close-up photos on your phone. I live in the city so there aren't many birding spots, but I tried it on a few trees and buildings and it worked great! In general, I definitely recommend it!
