100mm - 4 inch dia Standard Quiet Powerful Bathroom Extractor fan Shower Wall Ceiling Mounted Ventilation Damp Environment Control for 100 mm Ducting Simple Silent Toilet Ventilator Easy to Install

Excellent, looks nice and tidy against white tiled wall,nice n quiet,easy installation would recommend

I would have liked this to be more compact and nearer to the wall when fitted. It stands off the wall about 2 inches. Unlike my shower room fan which is neat to the wall. Otherwise it works fine.

The fan was easy to install. It looks neat and works well. The noise level of 25dB is acceptable but is not silent.

Unfortunately when the electrician wired in the extractor fan it didn't work; he said that the circuit board was faulty and wasn't working. There seems to be no way I can return this via Amazon - despite trying all the various options via the website.

The extractor is spoilt by very small connection block. The cover clip is poor, held on by a very small screw.

fitted this yesterday, straightforward if fiddly, NOTE this HAS a run on timer - other near identical looking models dont, also worth checking if you are replacing as I had to a 3.5 inch dia unit , this is 4 inch so you need to a) make the hole bigger and b find an adapter to go from 4 to 3.5 inch for the hose connector. but its a good unit not silent but very quiet and indeed a powerful effective extractor fan.

It is a bit noisy, but it does the job well

The main reason I bought this is because it was advertised as quiet with 25 dB(A) output. Well we've measured it at 56.6 dB9(A) and it is definitely not quiet. Only just got to install it so outside of returns window with Amazon. It looks good and fan sounds powerful, but it is definitely not quiet as described by seller and Amazon.
