Review: It’s a fan. It blows!
Review: The fan is strong as hell just be careful. There is no grate on the back. I went to adjust it in my plant cabinet and gave myself a blood blister. Also, I read the other reviews and sticking my finger in it attempting to pick the whole thing up and move. It didn’t break the blades. It seems to be sturdy. It definitely is a little noisy, but I’m OK with that with how strong the fan actually blows. my plants are gonna love it. They’re blowing around like it’s midday under the canopy in the Indonesian jungle. My only complaint is that I wish it came with screws so that I could mount it. I even bought a stand that fits this size and the stand also did not come with screws so now I have to guess what size I need.
