Title: Very good thermal lens.
Review: With the strange temperature variances between winter and summer here in Nevada a good thermal lens is a priceless piece of equipment no player, woods or otherwise, should be without. I did have a problem after six months. The lens actually split in a few places. I used it in an X-Fire goggle which is very flexible and my have gotten crushed in my gear box. Still a great addition to the line of compatible goggles.
