A good choice for this type of fan, always presuming it lasts.
4/5
70cm unit is easily fitted in a 80cm wide bridge unit. The hole is cut using the template. Then the switch/surround/grille unit is detached and the casing/motor unit fitted first. If being fitted to a unit already on the wall, the fittings enable it to be a one man job held in place while being screwed. Then the rest is clipped in place. 150mm ducting helps efficiency but is quite difficult for DIYer to put through a double wall. Needs a 152 core drillbit, an extension and a very powerful drill.
The extractor is powerful, if a bit noisy on the top setting. Being a half hob depth unit, it needs to drag the steam in. It easily lifts stainless steel gravity flaps. Well made though the plastic switch panel could look better.
I've deducted a star through sheer irritation at being made to clean up mesh covered in dirt-attracting glue from an unnecessary warning sticker.
