Avoid/ No support
"I liked the P17s. Bought them and never got any support because they broke both arms deteriorated not from physical but from working in extreme heat Iraq. I asked for a replacement but when a soldier buys them and goes on deployment or work trip/ Whiley warranty and Support go out the door! Thanks. The glasses would've been nice if they didnt just break from heat melting them off my face! What?1000 bucks and no support for glasses and a trophy of what not to buy? Avoid this brand. Yep -A Texas Vet."
