Me encantó pues es ideal para mi pecera. Mide bien la temperatura

Easy to install and read,a reliable item.

This PAIZOO digital thermometer has been a great addition to my reef tank setup. The display is bright and easy to read from several feet away, even in low light. It updates quickly and consistently matches my other temperature probes within a tenth of a degree, so I trust the accuracy. Installation is simple — just attach the sensor to the inside of the tank and mount the display on the outside glass. The cable length is generous, and it’s neat enough to keep your setup looking clean. Pro tip: mount the probe away from heaters or return lines for the most stable readings. For the price, it’s an excellent piece of gear — reliable, accurate, and perfect for both freshwater and saltwater aquariums.

Great little device!
