    • Not accurate
Review Image by Dave Dave
I should’ve known more Chinese garbage. I have three other sources to read the humidity. They all say it’s 60% relative humidity. This piece of garbage says it’s 84% humidity. It’s smaller than you would expect probably half the size again more Chinese garbage I’d give it zero stars.

    • Great for terrariums!
This is great for terrariums! It's a little cumbersome, but it does the job. I like how it can be programmed to set humidity and temp levels, air flow levels as well, its well worth the price. I also like that its quiet, i had to look at the unit to see if the fan was running to make sure because I couldn't hear anything. So far its great, I just hope it lasts a while. Other units similar to this one were cheaper, but did not last more than 2 months. So I. Hoping for the best with this unit. ... show more

    • Good fan for the price with small gripes
Good solid little fan for the price. It's small size is perfect for my indoor tent. I did in fact get this fan for its built in humidity monitor, and it performs well. The durability of the fan itself is fine. But not the USB-C power adapter it came with. The length of the wire is very short, it was hard to work around. My cable broke within a few weeks. My solution was to find my own 10-foot cable with a charging block. My only other complaint is that there is no on/off switch for the oscillation,. Sometimes I just want to move some air around my plants instead of directly onto them. But it permanently oscillates. The product would have been perfect if it had this small feature. ... show more

    • Great For Home Gardening
Perfect for seedling trays. I was using a big fan but had to keep adjusting distance as not to over power my seedling starts. This little fan is perfect for several tiers of starts that need hardening off.

    • Oscillating or not. . .
I don't know how to turn oscillating on, some people complain about not being able to turn it off. Problem is they aren't bothering to teach us how it works.

    • I mean...it works? Lol
Okay so the product it self works tremendously. Fan speed and air flow are great. The sensor works just fine. I can't really give this product less than 5 stars, but if there was one thing I could dock points for it's the not so tremendous user manual. It's almost like you have to guess you set it up the correct way. The only thing you can control with this is just the humidity level, not the temperature. ... show more
