It is not very powerful to start with. Within four months the fan would barely spin. I ordered another on line for around $50.00. The replacement fan is still working, but it is still underpowered. If you need one for apperance its not too bad, but if you need it to function you will be dissappointed. Their customer service was of no help either. The lady laughed at us when we tried to explain the problem simply replying she would need the documentation received at purchase. I explained we werent looking for a warrenty replacement, we just wanted to purchase the fan motor. I said why would anyone beleive they would need it for a range hood. So with the model number off the box she still couldn't identify the part. I snapped a picture of the motor with my phone and found one on line the next day.
