Very Good Optical Quality. Well Balanced

Very good optical quality. Precise focusing. Well balanced Haven't tried it in rain or bad conditions, yet. When locking the central focusing wheel, sometimes have to jiggle the wheel slightly. Doesn't appear to impact sharpness of image. The adjustable eyepiece rings may be a tiny bit loose. Don't have enough experience with binoculars to know what is acceptable play. Doesn't bother me or impact performance, as far as I can tiell

Quality without the huge price.

These are the nicest binoculars I have ever owned. Love the close focusing ability and the overall look and feel. The only thing that I would consider a minus is the weight. I was told you couldn't get decent binoculars with paying well over 100.00. These prove that that you don't have to pay big money.

Binoculars good

Low cost yet feels durable and precise. Get a little motion sick using though. May be due to a combination of handholding the binoculars, long focal length, and being a beginner.

This is the 4th pair of the exact binoculars I've bought. The first was for our boat, the next 2 for my son-in-laws and this last pair for our home! Everyone that uses them loves them! It's a fantastic product with a great price!!

Great optics with close focus

These are great for bird watching, and any other relevant purpose. The close focus is great for viewing at my yard feeders, that are too close for many binoculars. The long eye point helps with eyeglasses. They are lightweight and waterproof, and have excellent optics with accurate color transmission. My previous binoculars, by another maker, didn't transmit reds well, so cardinals looked brown. A lot of product for the money.

Extremely good optics

Extremely good optics, intelligent focus and ocular separation design as well as easy to use case and lense covers. I have a pair of Pentax 7x50 marine binoculars that I bought new 45 years ago and we still use them.
