I exchanged that unit for another from the same supplier and received lot number 9CJ323 (same), serial number 03553 (25 later). It had the same problem so this time I requested a refund. The problem was easy to replicate by keying 1 ENTER ENTER ENTER + + + ... and watching the display count by 1. Frequently it counted by 1 on both the key press and release.
