Tetra 25°C Cool Fan CFT-60 (3 units + 1 junk unit)

This is a listing for three Tetra aquarium cooling fans plus one defective unit.
I am no longer keeping an aquarium, so I hope these can be useful to someone.

These fans were used normally, so they have dirt, scratches, and age-related wear from use.
I performed a simple cleaning before taking photos and tested the sensors and fan rotation.
All were operating without issue, so I believe they can be used as is.
[Important]
One fan has a broken metal clip for attaching to the aquarium. It cannot be secured to the aquarium as is, so it is being sold as defective. However, it can be used without issue if you can find a way to attach it to the tank. It might also be useful as a spare parts unit.
*All wiring is connected and bundled with zip ties. You can use them as they are upon arrival. Please be careful, as reversing the wiring will prevent the sensor from operating and cause the fan to run constantly.

Before purchasing, please check the product manual for the CFT-60 online and then participate in the auction.

[Shipping Method]
*Please note that anonymous shipping is not available as delivery will be via Kuroneko Yamato. (Unfortunately, I can only ship from my home and cannot use other shipping methods.)
●I have allocated extra days for shipping, but if the timing is right, I will ship them out sooner.
