NOT RECOMMENDED!
We purchased this item in April. We've used it very little and it is not not working at all. We have contacted the seller three times for help with troubleshooting or a refund with no response. Amazon will not support a return claim because it has been more than 30 days since purchase.This hood is manufactured in an Asian country and contains no English wording in the manual. NOT RECOMMENDED!
