This LED lights did not stick to my walls. I set them up in my room (efficiently, I made sure they shouldnt fall off) and left for a couple hours. When I came back they had completely fallen off. I messaged them to see if I could get my money back or if another one could be sent to me because I thought maybe the one I received was defective and they never even responded and its been 2 weeks.

Ex Output:
negative

Ex Input:
The shell is flimsy and brittle with flaps that don't sit flat and a shape that doesn't sit square. The design relies on single snap-button connections on each side and pop-out hangers for the fabric liner. To much glare for what I needed.

Ex Output:
negative

Ex Input:
I can't believe the distance on these things. I purchased them to communicate with my Indy film crew and they have range. Example: Shooting a short in a four story building crew on the fourth and crew on the first floor about 3 football fields away. Cristal clearly Ear

Ex Output:
positive
