I can insert all my router bits and pick the tray up because it securely holds the bits in place, you could even tip it over and bits wont move. Stopped charging and won?t charge at all. Overall very satisfied, and I absolutely love the earthy beige color. Depth of field is very narrow especially at close focus. Good product , good quality . They sound better than my Jaybirds, more bass no shrillness when I listen. It is a story of perseverance. Like I said it gets the job done and doesn?t look half bad! I take a 6 and purchased a size 6. Material on top keeps them cooler, not fleeced entirely.
