I always opened my non latch box in that one direction, to promote stability, as the "pin hinge, is off center toward the right, so it always made sense to me to swing the window open toward the left.. the direction now allowed by the box with latch.
There is enough spring in the hinge pin to allow the lid to move over that ball easily indefinitely without wearing down the contact point.
Very few people embrace change easily.. me least of any, due to a head injury.
I had my doubts on the first day. I used the box for 48 hours.
I now find myself, adjusting the top on the box with no latch... to make certain it is centered!
I adapted!.
I love my boxes, and would not give any of the 4 I own up... but, if you are really unhappy, call them and ask.
Maybe even list it in the "Sell your vape or accessories " thread.. and specify you would like to trade. I am sure someone that wants a latch on their box will pop up if the MFLB or BlissSville folks can't help or give suggestions!
