### ⭐⭐⭐⭐⭐ Good safety tool
*by D***N on 17 February 2026*

Useful bit of kit for an aquarium using CO2, not a perfect way to measure CO2 but good enough to keep your fish safe and your plants growing optimally. Looks good in the tank too.

### ⭐⭐⭐⭐⭐ They are glass which is perfect.
*by D***C on 17 October 2025*

For the money these are great. Does exactly what it says on the tin.

### ⭐⭐⭐⭐ Cheap and work
*by D***S on 29 August 2024*

You could criticise the quality but to be honest, they work and they are cheap. Handy as a two pack for replacing when you are fed up cleaning the existing one. I will buy again. I was looking at the different types/different shapes. But to be honest, the traditional shaped ones are the best.
