After I've bought the EXENTRI Wallet I still had a retention of the coins found ... was ultimately able to find in the Monnibox and am very satisfied so far! The exact Cent Pay at checkout at the grocery store works great! Sometimes something hakelig is the removal of the last coin from the respective Specialist, here clamped before the spring mechanism ... with a little fingertip feel this can be largely Avoid! Here some potential for improvement would not exist - because of the low price still a nice gadget and 5 star!
