## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect size for smaller tanks
*by M***H on August 1, 2024*

I wanted a small size drop checker for my 2g nano tank and this one is perfect. As a back up I also ordered the normal suction cup drop checker and it was way too big and took up too much valuable real estate in my tank. The only issue to be aware of with these external hanging drop checkers is the entry point is much smaller than regular fluted drop checkers so every now and then I find a co2 bubble blocking the entry point which causes the reactive liquid to turn yellow (since no oxygen is able to enter). Your best bet is to place this drop checker away from your diffuser so bubbles to float directly into the drop checker.

### ⭐⭐⭐⭐ It works but surface tension builds up over time providing old readings.
*by C***Y on May 21, 2023*

You have to shake it to remove the tension to get accurate readings a few times a week,

### ⭐ Size is really not accurate
*by M***A on December 21, 2024*

This product is probably made for tanks with rim. There is no way the size is as described. It’s way bigger and too far apart. I have a rimless tank and this is way too big. Wish it was a smaller in between so it wouldn’t look so weird on the tank.I’ll be returning it.
