Small Low profile rotary roof vent for vans buses - BLACK - wind driven rotating ventilator

This was a replacement as I've just put a roof rack on and my Flettner vent sits proud.Cost , good value was concerned as it was half the price of my Flettner ....which is the gold standard for vents (in my opinion)Bought this as the fit was the same diameter cutout of the existing hole.The unit was easy to fit.....required only one bolt to be tightened to secure to roofSpinner is preset so spinning resistance cannot be adjusted....it spins freely with no bearing grumble.....was impressed with this.Have seen some reviews stating it rotates poorly......all roof vent i have used are like this until they have had a few weeks to bed in.The only thing thats missing is guidance to paint the cutout with a rust type treatment so you don't get a rusty roofGood quality plastic, freely rotates with no friction easy to fit.The roof vent is fitted to reduce condensation.Would recommend as its good value for money

No noise when driving and it's still in place so happy for my purchase 🤗

Was very easy to fit and works well

Doesn't spin unless I spin it myself

The vents were easy to fit.The holesaw provided was too small though.

Replaced an old one in 5 minutes flat, decent quality and does the job.

Perfect for our needs

I bought this to replace an earlier one that got busted - simple to fit - cut a hole with an electric jigsaw - silicone round the hole inside and outside - put 2bits together and 1 screw up the middle - simple
