Not quite as stated
Doeznt fit 100mm or 4" ducting . Its very loose and not airtight . I had to use duct tape and silicone to seal . Also plug is usa not uk so adaptor or cut plug off but very thin low volt wire . Will reserve judgement on how long it will last

Sold on .co.uk comes with moulded US 2 pin plug (no mention in advert)
Seen the good reviews so thought I would try it. Unfortunately I cant test it due to it having a US plug. So I either need to buy an adapter which will add to the total price or return it. As it feels cheap and I doubt it would last long I think ill send it back and buy a proper fan for a bit more elsewhere.
