Review: Game Changer - Seems Like it’s Legit and Not a some desertcart Counterfeit. Works as intended and Believe it will be a GREAT help. Thanks AC INFINITY ❤️💯
Review: Almost perfect - Great tool to up your game. Perfect quality. Comes with everything as advertised. Only negative I can think of is the instructions it comes with are not clear regarding how to pull the trigger... I mean: should I keep it pressed for a certain amount of time to get the reading or is just a quick press and release enough? Any how, this tool helped me realize I had a way bigger temp diference between leaf and amb temp than I thought and my VPD calculations were a bit off, and it saves me alot of calculating. It's completely worth the money. I got it witha discount, but would pay full price without hesitating. Thanks ACI!!!
