These phone zoom lenses are really cool. We reviewed this 4K Pocket Monocular Phone Telescope recently and were shocked at how far you could zoom with it. Feel like taking a photo of the moon's surface? What about that guy sailing on a boat in the bay? I'm sure you can think of a million things to do with this.
Planning a hike? Bring this along. Better yet, check who is already at the top of the peak and send a smoke signal you're on your way up.
Gift Tip: This gift would suit tech or gadget enthusiasts, travelers, wildlife lovers, bird watchers and beginner astronomers.
