Meter Upgraded: Quantum PAR - High Precision, Grow Light meter, Indoor Plants meter, Good for Growing droseras and All Indoor Plants

The wire grommet out of the unit to the sensor pulled out of the body exposing the very fine wires to the sensor. Another review also noted the same problem. That happened after a week. The meter also reads considerably lower than a friends Apogee meter. You get what you pay for I guess. I'm in the process of returning it for a refund and they want me to pay for return shipping. Poor customer service!

This works pretty much, though I have no other PAR meter (e.g. from Apogee) to test its accuracy. But I've tested it with some android apps that give close approximations of PPFD readings using my mobile phone's light sensor (i'm on a samsung galaxy ultra) and the readings are pretty close to this PAR meter's readings.Have yet to figure out how to secure further that cord that others encountered an issue with; I wouldn't want my cord to loosen or disconnect (fearful) as what others experienced.Overall, a good alternative buy!

Como medidor PAR me daba lecturas dudosas, pero las buenas lecturas algo tan barato no las obtiene. Y se rompió pronto. Los cables principales se despegaron. No vale la pena comprarlo. Terminé comprando un Apogee que aunque cueste el doble es mucho mejor, más duradero y más fiable.

Great umol meter, can’t grow without one. Had an issues with my meter. Unfortunately for me the warranty was about two months past the expiration date (1 year). I emailed customer service anyway which they responded immediately by saying that they were shipping me a replacement meter . Great customer service. I couldn’t be happier with their service. If you’re looking to purchase a par meter this meter is great at an great price

I like it cuz seems to work perfectly but how long it will last or the cost in comparison to the manufacturer cost to make it seems way over priced . Seems almost like eBay quality with premium price tag
