Product review (5 stars): One of the best investment and great custom service.
One of the best investment I made given we cook Indian food at least twice a day :)  Fan/motors are very powerful and almost eliminates cooking smell. I like the auto-sensing feature which detects gas/smell leak. Many time it has saved milk/tea overflow because it turns on the fan which remind us to take an action.

After a year, the gas sensor broke and I contacted customer service. They immediately shipped a new gas sensor. While inserting this gas sensor, it blew up the circuit-board and they shipped a new one immediately.

In short, customer service is great. Thanks Alex.
