My cockatiel has a lot of problems so I wanted these tests to see if they showed anything. As you can see, the test results are within the safe range. I took tests every two minutes. What I didn't like about these straps is their fragility. When I opened the container I noticed that some of the strap squares were missing. I pulled the strip out to look at it and put it back in and the square came out too. So don't rely on the full 125 straps. Luckily the squares in my aquarium didn't fall off. I wouldn't say these tests are good, but they're not terrible either.
