Signs came on-time and exactly as described. The plastic sign was actually more durable than I expected.

No more cracking

Quality workmanship. Highly visible and won't slit and crack in the sunlight like the plastic signs do.

Radiation Sign

Nicely made w/great lookong yellow and Magenta colors! Easy to order and fast shipping! Pre-drilled corner holes are a plus. If there were a negative, it's the stamped Aluminun edges that haven't been shaved and are very sharp along the edges! Overall, I'm pleased with the company and this purchase, thanks!
