Review on AOBEN 3/8" 12V Electric Ratchet Wrench Set With 2000MAh Battery & Charger - Power Tool Kit by Chris Destruction

I finally got a chance to use this cordless ratchet and put it to the test for an automotive job (replacing rear brake rotors and pads). As many people have said - you cannot use this for breaking lose any tight bolts (ie like wheel lugs). You can use this for bolts already loosened. On my brake job, there was a bolt that was loosened but it was still stubborn to take off (probably had thread locker), this ratchet could not do the job. This would be ok to use for normal jobs that do not have stubborn bolts (ie does not have thread lock on it). I was thinking this would be a powerful tool because of how they advertise this product (up to 40 lbs torque , 2000 mah , etc.) but all this can probably do is work light duty jobs (ie putting a picture frame together?), quality seems ok and seems like it could last 2-3 years on light duty jobs, otherwise I think this would break or over heat the motor and burn it out.
