Review: Great Fan - very quiet. - Bought to replace a fan our builders fitted a couple of years ago which died last week. The old fan made a racket, so much so that we could hear it all over the house. I was 'getting around' to fitting a new (hopefully quieter) fab, but it never made it to the top of my list. So when the old fan died, I was quite pleased. Fitting was a doddle. Our builders had siliconed the last one to the tile wall, it never fell off, so I decided to do the same with this one. That meant i didn't have to drill holes. I used the same wires as the builder had used (making a note of which colours went to which terminals). When I switched it on, was very happy. Its so much quieter. Its not silent, but i cant hear it from the landing when the bathroom door is closed - so that's good enough for me. If you're looking for silence, and you're starting from scratch, you might want to consider an inline fan. For me that wasn't practical as the hole and wiring was already there. If you're looking to simply replace an existing fan, you cant go wrong with this one.
Review: Cheaper than retail - So my fan broke in my bathroom and I was annoyed I would probably have to pay a lot of money to get it fixed. However, I looked on desertcart and I found the exact same fan and a fraction of the price. When it arrived I was expecting a knock off box but instead it was the real item with all the additions provided. In the box you get the plastic cylinder to connect to the outside, the sticky backed fabric that seals around the fan, all the pieces you need to fix it, including screws. Once fitted it works perfectly, not very silent, but I never leave it on when I'm going to bed so this never bothers me. I live in a bathroom that does not have a window, so I leave this fan on for hours at a time after I shower to remove the steam. It does this perfectly with no malfunctions even after being on for hours. Overall great product, great price when I bought it, definitely recommend buying.
