    • 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

    • Little fan for tents
Good for size too small for me. Going for a bigger fan and filter now .. for tents with no airflow it's great any temperature gauge works great

    • This little fan is very helpful for an indoor grow tent or greenhouse!
My indie greenhouse trends to get so humid that water drips down the walls like rain. This little fan is doing a lot of work keeping up with it. I ended up having to move the greenhouse out from the wall a bit too mount it, but once I got it in place, I have had no issues at all. I'm very happy I got this for this year as I'm tired of the mildew scent that typically comes along with growing my plant starters! ... show more

    • Mounting system needs work
Yes it moves air. Yes it oscillates. Yes it mounts to a pipe. No it doesn’t fit very well between the bar and the wall. Keep looking.

    • mild breeze
I've tried this in my greenhouse and while it turns on and off perfectly, I found the strength of the breeze to be insufficient. I moved it to the henhouse where it will work as it's a smaller space to cool. The girls will appreciate being more comfortable this summer.

    • Humidity control. Yes, temperature control no
The hygrometer seems to work quite well on this device. The fan comes on the set humidity level. The fan does Not automatically turn on at a given temperature. I thought the description was a little misleading. The instructions are written in very small font with poor grammar and spelling. If you’re only concern is humidity level in your grow area than this fan is fine. ... show more

    • Handy for 2x2's or 3x3's. A rare oscillating small clip fan!

I need to conserve space in my 3x3 SOG, so this smaller fan fits the bill perfectly. It's actually hard to find a smaller clip fan that oscillates for some reason - but this fan does just that! It's a little loud on full blast, but it also moves a ton of air for it's size. I don't need to use it on full, slow and medium both move plants just fine! It's easy to use after figuring it out. I don't use the humidity or temp controls - with that said though it's VERY nice to know the humidity level and actual temp in the tent!! Interestingly the temp sensor is very accurate and must have a fast pooling rate because it reflects the actual temp very quickly. If you're needing a small clip fan that oscillates then this might be a good choice! I can't speak to the longevity yet though so you might try to catch it on sale in case it only lasts a few "seasons". I'd recommend! Oh yeah - and a few more things I wanted to mention.. The fan comes with a "charging base" which is kind of rare these days. It's a power base in this case but it can be a charging base for other stuff if you need it to be down the road. The cord is medium length - it could be longer but it's not bad. You might need an extension cord depending on where you have it. Lastly, depending on how you have it connected to your tent, it may bump the pole clamp when it's oscillating. It didn't seem to effect it though and I just adjusted it a bit and it didn't bump it anymore. ... show more
