IR Review

It took twice as long as claimed to receive the product with no communication from ATN. The tracking number was never active and then the thing just showed up one day. I only bought one because a friend of mine had one that appeared to be considerably brighter than mine that came with the nvd I purchased years ago. This thing doesn't appear any brighter than the stock one that came with my unit but it's just such a hassle dealing with ATN that it's not worth sending back.
