Bought as a Christmas present so unable to give details in use but had a quick look and they seemed an excellent good value pair of binoculars.
At least comparable to my Nikon Travelites with the additional benefit of being waterproof and anti fog.

Well built and sold with a complete kit. But it s quite bulky so if you are looking for a pair of real pocket binoculars i don t recommend the pentax. The vision is sharp the field of view a little narrow but the main issue in my opinion is the eye relief. Pentax declares 15mm of eye relief but i am finding quite difficult to use these binos while wearing my eyeglasses. For example with my olympus 8x25 wp II that have theorically the same eye relief of 15mm i don t have any problem. Also with the Celestron Granite 9x33 eye relief 14.1 i didn t encounter any problem but with the pentax up 8x25 i need to remove my eyeglasses.
