I have used Pentax cameras and lenses for a long time with very little trouble. The camera I use now malfunctioned after some use, but it was still under warranty. I sent it off and they cleaned and fixed it, and it has worked fine so far. So while I can't speak for the binoculars, the customer service wasn't bad. I like to take pictures of wildlife, so the camera had been exposed to the elements (sand, moisture, etc.). The My experience with Pentax in general has been good, so I would have no problem purchasing anything made by Pentax in the future.
