Pros: Fans are quiet; made with dual ball bearings and they seem to perform well. The cables have both male and female connections, a nice featue.

Cons: The fan cables are too short. I was able to use two in my Antec 300 box, but it was a real stretch and having the two connectors saved me. I doubt the cable lengths are given (don't recall), but beware! Dropped an egg for only this reason.

Pros: This is a nice product on the face of it, features and connectivity. Nice for use in a empty 3.5" floppy port.

Cons: It did not work! I tried to install on a new Win 7 pro system as well as upgrading to Win 10. I installed the driver several times, searched the net. There does not appear to be any support what so ever, based only in China.

Overall Review: Perhaps a product like this is just plain no longer of interest. It would have been useful to me if it had worked though.

Pros: Works like the others. Great introductory price. Hopefully it lasts.

Overall Review: Worth a try
