I changed the motor of the 3.7 volt mini rechargeable fan.

A few days ago, I changed a controlling circuit of this fan, which you can see in the video. Its price is 20 taka in Bangladeshi market. After changing the circuit, it was running for two months, then the motor had a problem.Then I bought a motor for our Bangladeshi market price of 30 taka and fixed the fan for another 60 taka.And the customer was very happy to receive this fan because the repair was done for a small amount of money, because our current market price for these fans is 250 taka.I hope you understand from my video and description that I was able to repair this fan very easily.
