Review: Very pleased - Very pleased with this, as usual with most things it's a minefield trying to choose which extractor to buy, I decided to give this one a go as it seemed a good balance of sensible price & decent reviews. I have to say it is really nice looking, looks and feels quality, it's probably a little noisier than some out there but not annoyingly so and I don't really mind too much as long as it does the job it's designed to do!, which I'm pleased to say it does!! It's probably the most effective extractor I've had, and we've had a few! Timer works well & it was nice and simple to install, fitted perfectly! Finally, I was really unsure about the blue lights and thought I might have to find the wire & disconnect them... but... I have to say, they actually look pretty good! All in all, after much rambling! It's a thumbs up from me, very pleased :)

This product is excellent very quiet not silent lightweight easy to use had it installed electrician said it was first class quality and easy to install very sturdy and looks superb

### ⭐⭐⭐⭐ Looks very neat
*by G***D on 10 May 2023*

This smart-looking fan is ideal for an interior toilet and this was the use I purchased it for. The final appearance is very minimalist and very contemporary. Good points: The fan has a 2-15 minute timer; I have found when set to the minimum setting the run-on time is actually around 90 seconds. It has a backlit blue-LED feature which lights up brightly when the fan is running, and very faintly when it is not. Not-so-good points: The fan is extremely fiddly to wire up, as the cable entry is tiny. Forget being able to use a 1.0mm flat 3-core & Earth; I could not get one to go through the hole and so ended up using a flexible cable. Access to the fan & timer once the unit is installed is also fiddly and so it is imperative that any adjustments & tests required are carried out before the cover plate is fitted on. It has a screw but also uses four little plastic lugs which, once snapped into place, are difficult to remove. It is not a noisy fan but neither is it silent, so if you want a whisper-quiet one, this is probably not the one for you. All-in-all the fan is a good value product that looks much more expensive than it is, but is not very easy to access for maintenance or repair.
