Reviews
Sign is good and glows fairly bright, but I noticed the corners started lifting a little after a few days outdoors. For indoor use it’s excellent; outdoors I might need extra fixings. But still worth the price.

I ordered this for my workshop door and it arrived quickly. The rigid plastic version is sturdy, and I was pleased to see it meets BS/EN standards. In total darkness it’s still readable. Very pleased with purchase.
The sign itself is exactly what I needed — bright glow, clear lettering. My only gripe is the adhesive backing could be stronger when stuck on slightly uneven surfaces. But overall it does the job well
I put this sign up in our warehouse loading area. It glows well even after lights go off, and the quality is solid. The message is unmistakable and has already helped reduce door tampering during off‑hours. Would definitely buy again.
