I got these for my husband who is pleasantly surprised by the quality, especially for the price.
Glass is very clear
Easy to adjust
Ergonomic, fit nicely in your hands
Lens caps are attached (so you don't have to worry about losing them)
Quality seems decent so far
Unsure if these are waterproof as it is not specified
Compared to my vanguard 12x 50 lenses, the focal adjustment seems limited, they look farther away in these
The left and right focus points seem to be different. Far away items can be in focus on the right side while up close items on the left are in focus (possibly a defective pair? Will contact the seller in regards to this.)
Given the price tag, they still deserve 4 stars.
