We are getting a new kitchen and I'm determined to get a very high extraction rate cooker hood due to my greasy stir frys. A friend recommended Kaiser so I'm looking at their range online. There's a built-in one (kaiser.co.uk/products/avantgarde-pro-built-in-cooker-hood-white ) which seems a lot cheaper than the standard 60cm chimney ones. I'm always a bit skeptical about the built in ones due to their much smaller size and suction surface area. But has anyone actually had experience with built in hoods please esp high suction power ones? Are they as good as chimney ones? Thanks!
