Review on WINSINN 50Mm Fan 5V, 3D Printer Micro 5 Volt Fans 5010 Hydraulic Bearing, Brushless Cooling 50Mmx10Mm 2PIN (Pack Of 5Pcs) by Jeremy Hudson

I bought these fans to use one to replace the dead fan in a cheap, Ebay bought smart charger. The smart charger has lasted over 3 years now, two of those years in constant use and only the fan has been a problem. Ive come to like the little cheapo charger so figured Id keep on using it if all I have to do is replace a fan. I doubt these fans will last any longer than the one that was in the charger to start with but you get five of these fans for very little money. Even if they only last a year each, thats 5 more years use of the battery charger-assuming the rest of the charger lasts that long as well lol! Anyway, for the price point, these fans are a 5 star product. They arent special, they probably wont last terribly long but they are super cheap and you get 5. Have realistic expectations when you purchase cheapo products and you'll never be disappointed.
