I gave these to my niece (she never tested her water before becasue she thought it was too difficult to do). I'm not sure what her results were (a bit secretive about it), but she said they have fixed the water and her fish seems happier....when the sample pck runs out she's going to buy more. Apparently the sales person at the store never told her about the test strips!

Pros: simple

Cons: ?

This sample could not have come at a better time. My betta was very sick and I needed to test the water. The water tested fine. Pluto later died from his condition but I believe these test strips were accurate. The only problem I had was that once the strip had been sitting out for a while some of the blocks had splotches of color changes that were not there before.

Pros: was very easy and quick

Cons: the colors were splotchy

I could not have gotten the strips at a better time. I was able to find out that my PH etc was off. This is why I have lost fish in one tank. The strips are so very easy to use. Just dip them into the water wait a few seconds and compare to the chart. I went online to see what I can do to correct the problems. And will be able to correct with drift wood.

The effectiveness is excellent! I hit the wrong star I guess.

Pros: Easy to use, quick results. Follow the directions...no mixing necessary

Cons: hardest thing was to get the chart off the inside of the label.

I received this sample a few weeks ago. I am overall satisfied but I think they could be more accurate. Some of the strips test differently than other even if I test them at the same time. But they are close enough not to make a huge difference. But I will still recommend these to anyone who doesn't want to deal with the liquid testers.

Pros: Fast

Cons: not always accurate

Quick Dip strips were great! No measureing or waiting. Just dip and read. Easy to read since a chart is included. Accurate and fast. (Checked accuracy against my PH Test Kit, Ammonia Test Kit, Titrate and Titrite Test Kit.) Quick Dip was accurate and took 30 seconds to read...not 15 minutes. I highly recommend Quick Dip strips!

Pros: Convenient, fast, accurate

Cons: Alittle expensive to buy
