Hi, I received lots of feedbacks telling me that hood is useless, but certain ppl told me its depend on the watt you had choosen, is it true?. Is anybody out there can advise me whether by installing a hood is necessary or do you have any experience on it? If so, may be you are kind enough to share with me your hood's brand and the watt you are using pr things tat I need to look out of. Thanks alot.
