Review on 🤿 Enhance Your Underwater Experience with Trident Scuba Dive Mask Magnifier Lens (Gauge Reader) by George Hersey

No glue or mounting template included. You have to guess which silicone glue to use and then _where_ to attach the lens and then clean the area contaminated by the "gluing" process. your computer when it is close to the lens. The lens itself obscures your field of view when you're swimming, making that [huge] area "blurry". Again, it's nearly impossible to remove excess adhesive around the lens area without scratching the mask; To see the computer you have to bring it close to the lens - almost useless if you have a dive plan and need to follow it. You can't bring the computer close to your eyes every few minutes. if I could do that, I wouldn't need a lens at all; - literally impossible to remove the lens after realizing my precious mask was almost ruined.
