Good fan

### ⭐⭐⭐⭐⭐ Stylish and good quality

Good quality, looks good, easy to fit.

### ⭐⭐⭐⭐ Nice. Good price point and target market.
*by A***H on 26 May 2026*

Excellent, nice quality and nice price point. on par with brand names and a more sensible cost. average noise. The anti back draft was a bit of a disappointment being a thin sheet of plastic but works. Nice the adjustment tool is located inside the housing but unfortunately got in the way of my incoming cable, so I've lost it already. Would be nice to include a bit of sticky foam to make a good seal around the neck but I would buy again.
