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

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

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.

Definitely NOT silent and no run on timer even though instructions allude to their being controls under the mains supply. There are none. As such all you get is a noisy fan that runs constantly.

I had always used another brand for installing extractor fan, however, and having installed this model, I am very impressed. It's very quiet, extremely efficient and removing excess moisture, and the humidistat is probably the best I have come across. It's a bit awkward to install, this is largely due to the ridiculously small wiring contact points, but this is only a minor issue. Other than this It's a great but of kit.

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

Works well and easy to install. Happy with design and looks a bit more modern than some. Not sure if its quieter than old one but it's in a bathroom so not a problem.

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.
