    Great fan / light, resistor burnt out for leds but quickly replaced by Sterr, very pleased
  

*by S***. on Reviewed in the United Kingdom on 4 June 2020*

Great fan and led, looks brilliant, very easy to install if replacing an older one, night light LED bright enough not to use main light.Bit expensive but looks the part.Down side, only been installed for 6 months and LEDs went dim took it apart to find the resistor burnt out on the lighting circuit board.On reading other reviews, these have issues burning out other resistors aswell to the point of ignition, this however was not smoking but had burnt out.I have written an email to the manufacturer and heard back very quickly, Sterr were very helpful and came back to me straight away, I sent an email of the damaged resistor an they sent me new pre wired circuit board to replace arrived in 5 days, fitted and working fine again. Excellent customer service

*by M***R on Reviewed in the United Kingdom on 17 January 2019*

ok people say its noisy , sounds pretty good to me, timer wont work, ummm yes it does , i wired it up straight away it worked and timer was on 2 minutes as stated in booklet so unsure as to why people say it wont work, maybe wired wrong or ordered one without timer by mistake.light not bright??? .it's not meant to be bright it is decorative ,thats why you have bathroom lights, some people are never happy,bottom line isquiet? you can probably get quieter but it is fine to me ,timer works  just order the right one and wireing is easy,bright lights??? sorry not a disco gives off a nice glow and i have bathroom lights to see what i am doing.would i recomend this fan? only installed it an hour ago but yes looks nice , will do what it says
