Review on High Power 12x50 Handheld Monocular Telescope: Waterproof, Portable Scope for Smartphone with Universal Adapter & Stable Tripod - Ideal for Hunting, Birding, and Travel by Jelani Weaver

I am paralyzed and bedridden. So I like to feed the birds behind the sliding glass door. It wasn't an ad, but someone on YouTube spoke of an amazing monoscope for less than $30. Searched at Revain, found it, bought it and I'm thrilled. The clarity is great and when you plug in your IPHONE it's at the perfect distance to take pictures. I am shocked for my money. But nothing is perfect: What I don't like: 1. The eyepiece cover keeps falling off. Too out of shape.2. There is a spring loaded slider to hold the phone. I have to take my phone out of the case to fit in the slide. It's really tedious, so I take some shots. Conclusion: you have a great product that is worth the money. Increase the width of the slider to accommodate phone cases and tighten the eyepiece cover to achieve perfect results.
