## Customer Reviews

### ⭐⭐⭐⭐⭐ good job
*by S***A on December 20, 2020*

It works fine very well thank you

### ⭐⭐⭐⭐ Does not measure necessary PAR
*by A***R on January 3, 2021*

They imply it measure UV bands that prevent insects and bacteria , thought these require UVC which is <280nm. UVB is most beneficial for flowering and that is a range of 280-315nm. And UVA which is best during vegetative growth is 315-400nm. So it will barelyyyy measure any UV at all actually. Tricky marketing tactics. But still the best on the market, hopefully they can further increase the range of measurement in a newer model!

### ⭐⭐⭐⭐⭐ Can't beat industry leader in PAR Meters
*by J***  on December 27, 2020*

Apogee quality quantum sensor delivers extended range readings of PAR vs cheap lux meters. This is what you need to dial in your system. Except nothing less!
