### ⭐⭐⭐⭐⭐ Binocular rain guard
*by A***R on October 16, 2025*

Good product. Fits my binoculars. Very reasonably priced. Hope I do not lose these!

### ⭐⭐⭐⭐⭐ Good fit for Nikon Monarch M5 12 x 42 binocs
*by R***O on November 29, 2025*

These are good snug fit for my Nikon Monarch M5 12 x 42 binocs

### ⭐⭐⭐⭐ It's Okay
*by J***3 on September 15, 2025*

This eyepiece protector fits my binocular eyepiece fine. It works but I'm not overly impressed with the left side binocular strap holder. It's an open ended holder for that side strap, instead of being closed-ended like the other side. The design for that reason is not great, but I will say that for being China made, the rubber seems to be of decent quality, though I haven't used it yet in the field.
