It does the job! You can't beat the price as it comes with a drop test solution. Sufficient for 2-3 fillings. The suction cup broke the first day but has been fine ever since. I'm thankful for this simple CO2 measurement solution as it turned yellow on day one, telling me to turn the regulator off.
