I had a third gen. Inforce WML in the sand colored polymer. I knew that there had been reports of the sand polymer cracking, but it was a screaming dream on Amazon compared to the black and FDE WMLs and I needed an IR light for NV.
Anyways, the polymer begins to crack near the bezel, I finally get around to contacting Inforce on September 30th, and after a few exchanges of emails that day I have a RMA and their customer service rep has asked what color light I want for my replacement since they are no longer making lights with the sand colored polymer. I think I returned the cracked light on the 3rd or 4th.
Yesterday the replacement shows up. They sent me a Gen. 4 WML to replace the Gen. 3 WML and the Gen. 4 is a noticeable improvement over its predecessor. The toggle switch between IR and Vis feels tighter and locks into place requiring slightly more force to change. The safety now locks into place with an audible click sound.
Anyways, a fantastic customer service experience and they replace a defective product with not just a working product but an improved product.
