Just installed their X800 model range hoods two months ago, the results are very good! Highly recommended. The sales staff at Fremont gave him five stars

I bought a 800 pro model. After we installed the product, the fan creates an up and down sound which is annoy. the shop told me that either the flow of our pipe is not enough or we need to take out the panel on the product that may block the flow. They said they will not let me return because I installed the product already. But how do I know if this is a problem if i did not install the product! is it possible the product is defective! When they sell us the product, they did not mention requirements like this. I dont think my house is any different then others. my pipe is 6 inches wide like the sales guy mentioned. What should i do? Should I dispute this on my credit card?

Very good shopping experience, we bought a range hood there, the price is very good, the sales staff is very patient to help introduce and explain, we are the new house, there are many places do not understand, she is willing to help solve our problems, thank you so much for her help, her name is Crystal. Ill share it with my friends.
