Looking into picking one up to try and get an accurate reading on leaf surface temp once and for all. I have some digital thermometers but I can't say I can rely on them too much since if I lay them on their back, facing the lamp, they blast off into the 90's but If I stand it on it's side, at the same distance from the lamp, it stays in the low 80's. Who has used them? Who likes them and who doesn't? What have your experiences been as far as accuracy? I'm trying to stay under $100.00 on this. Any feedback is appreciated as I'd like to order one ASAP and could use some recommendations.
