It looks amazing! I haven't had the time to hang it yet but the stuff they put on there for me looks awesome!!!!!

Lawrence P

I love my sign. I honestly spend way to much time playing around with it. When the time comes for a bigger outdoor sign I will come back to the good people of Best LED Signs

Michael Marty

The product is superb, and their service is excellent.


The pictures don't do it justice. It looks INCREDIBLE in person. I've only had it for a few weeks but im really considering getting a larger one for the outdoors after seeing this.

Amazing customer support

Lighting struck the roof of my business and fried all my electronics, including my sign. The people at Best LED Signs were kind and understanding and sent me out a replacement battery for my sign at no charge. It wasn't difficult at all to change the battery, and after that my sign is working good as new.
