We got the 290 for our small bathroom and there’s barely any suction so it’s effectively useless. We checked the specs for the room size, had an electrician install it, and made sure it had the best chance of maximizing suction, but it was still useless. The bathroom is completely steamed up within a few minutes of a shower. It’s also not as quiet as it’s made out to be.

On the plus side, Lighting Outlet were great in their customer support, and the unit looks nice, but the product is poor.

Would not recommend buying.

I purchased this Martec fan to 'match' a smaller one installed in the toilet. While this fan externally matches the look, it is no match to the smaller version in the build. The exhaust vent on this fan clips on, and found it kept coming un-done from the fans force, while the smaller one screws on. We had to tape the exhaust vent onto the unit to fix the design issue.

After a few weeks the nut holding the fan on came loose and the fan was rattling around. So again had to 'repair' another fault.

Otherwise the fan sucks well, not whisper quiet as some claim.

Generally don't mind Martec products, but this one is pretty poor for the price.
