The build quality looks pretty much the same as the other two (Manrose) I've bought over the last year. I've posted a couple of photos of the packaging. As far as I can tell it looks up to scratch.
Thanks to the posters confirming that L and N can be either way.
It says Made in Poland on the box but it was bought from eBay. The instructions are a bit vague and doesn't note that there are two wires with the same colour. It does have some Russian instructions too.
So I can put live and neutral into either? I did wonder if that was the case, but a couple of other extractor fans I've installed did have coloured coding for L and N e.g. Brown and Blue.
I've got a replacement extractor fan for my bathroom. it's a basic model, no timer or humidity sensor.
I was surprised to find the wires for live and neutral are both the same colour blue though, as shown below! Can anyone tell me how to find out which is which?
