Julius awesome ,

This is easy to use and great functionality

I can’t be happier with this app feature for my Lander smart lantern + power bank

Already used it on travel for mission trips and a study light for the bed

Going to get more and tell my friends to get some so we can all sync it up for a rave! Jk but would be cool! For a camping event!

Moosejaw sold me on this product and it’s amazing!! Y’all

Charge those cellular devices like they are nothing to worry about!

Good idea but buggy

I recently bought the lantern for our family tent as I liked the idea of controlling the light from my phone. The lantern is well designed but the app does not reconnect automatically and I have to restart the app each time for it to find the lantern. This makes most of the neat features like proximity mode unusable. Great concept and solid light but might need to return it to REI if this bug isn’t ironed out. Also doesn’t look like the developer has pushed any updates for over a year, never a good sign...
