They were good they function well just didn’t work out for what I was hoping for what I was using them for

I bought these for our gecko's small enclose to help regulate humidity. The 3-speed setting is helpful and it's near silent at all speeds. It's a pretty specific use case, but the size and quality are perfect for it.

So far so good! Using them to ventilate a tiny greenhouse and seem to work just fine.. quiet too!

Whisper quiet, and surprisingly good airflow for such small fans! I am using them on the low setting to cool a small audio amplifier. Works extremely well. The description doesn’t show it very well, but there is plenty of cable to work with.

Item as described. Works for what I needed it to do.

It was not powerful enough for my requirements.

Very small, but work good on high.

Using this for a Vive Wireless Adapter to keep it cool. There's a thingiverse design for a similar dual-fan product which I haven't printed yet, but I'm excited to try it. The fans themselves work well. The noise level is a little higher pitch than I expected, though. I worry that this might be a sign of the fans being roughed up during shipping or something like that, but they work really well and are cheap, so I'll use them until they fail. Not much else can be said about this product. It's 2 fans with a long cable and a switch. It's easy to power and easy to find a use case for.

Petite fan tres efficace , reglabes 3 vitesses peu bruyante parfaite pour une enclosure de mini pc.

Exactement ce qu'il me faut vraiment silencieux même a fond fournit avec 4 visses de montage et 4 visses aux grillages
