Review: Recommended - Seller very helpful! Looks good. I have 2 cores cable, so i choose with humidity sensor. Works well, turns on from humidity level
Review: Not cheap but the item is cheap - Terrible waste of money, the fan wouldn’t switch of after 5/6 days, it was fitted by a professional electrician, I complained about it and all I got was send us a picture, so I did, they said no a picture of it with the wires out, it would then have cost more money to take it out than buy a new one, my electrician told me twice it wasn’t working, I’ve still not had a refund , do not buy this item unless you only want it for show 🤬🤬🤬🤬
