  1. YES I have read the terms and agree to them
Selling BNIB Hanna Magnesium Checker model number H1783 V2 (this is the recall replacement). I had the original one that had all the issue with expired reagents, I filled out the recall form and received 2 replacement checkers. I contacted Hanna to see if they wanted me to send one back but apparently they had me down for 2 and told me to keep both, so one of them I am selling $54.00 dollars shipped.
