I was not sure I would need this forehead rest on my 8X42 model, but I was pleasantly surprised that it actually offered some additional stability.
It also pulls straight off the bins, it you ever need to remove it quickly.
S&S sent this out to me on the day of my order and I received it is just two days.
You couldn't ask for more.
Great addition for the NL Pure binos. Definitely helps steady my 12X Pure binos, especially when glassing one-handed. Very happy with the purchase, works great.
