I expected a higher failure rate sorting. 50 Coins is a 1 cent piece after it firmly stuck at the ball - was probably not completely clean - and by briefly shaking was free again only fallen into 2 cents times. Then we briefly opened the cover to the plastic key and re-sorted by hand. It fell out of nothing, is going well. Otherwise all other coins have been sorted correctly. That'S Fun. The plastic key looks weak. Yet he does it ... Despite the bad key, I think 5 star to be appropriate because the Order works reliably.
The part was after 4 weeks down on parquet floor - plastic cover is cracked, poorly patched with tape. Keeps holding out much.
