A couple of people have reported this. There’s also been a couple saying the same thing on the Clip board. I would say it is NOT indicative of the entire line as only a few people have said anything about it. If this were a major design flaw we certainly would hear much more about it than we do here.
I would consider this an isolated or occasional defect and if you get one that does this, return it and get another one. There’s only been less than a hand-ful of posters claiming this out of literally hundreds (or more) of satisfied customers. Many even have more than one.
