Would never recommend. I bought it because it looked simple and was easy to use. The tester said it was 3.3 dch. I started taking more and more every day. Eventually things started dying so I decided to take them to the fish shop to see how accurate they were. DKH WAS 17. That's so high! I CHECKED THE DEVICE AGAIN AFTER THREE AND IT STILL SHOWED ME 3.3!
