So happy to have gotten these. I paid around the same price price for 10 test strips at a local retail store and it has 2 more tests included for a total of 10, but for what I need this covers all and I get 100 strips. The value difference here is huge.
My main focus is testing for copper since I have high free copper when I had blood testing so it is important for me to constantly check. Something interesting was noticed. I know I do have copper in the water because there is colouring around the faucets as the house has old copper piping. It seems to be minor though as it doesn't show up in drinking water from the faucet without a filter.
So the interesting thing was that the water from the faucet was fine, but when I tested my water filter, I had trace copper! So I had been using the filter to avoid potential copper and it seems like it had been leeching copper in the filter and pushing it out. Very good to know this so I could switch to a new filter.
Really happy with this and I get to test constantly without having to buy expensive tests!
