The MPK Star M Pro Vent is an excellant easy to fit roof vent. My units were used to replace existing fiamma units that had broken. The 400 x 400 holes in the roof matched up exactly, and all the fixings matched up nicely. Looks really neat and easy to use.

This was my first order from Rainbow Conversions & I'm very impressed with the service I received, as for the MPK Vision Vent Pro, this is a fantastic vent & looks awesome Above the alcove bed, I had no problems fitting it to my Motorhome,

Very good service and pleased with the product, chosen in preference to others.Bit of a problem fitting as the Transit van roof is not flat. Instructions could be clearer

Good product easy installation better than the original roof lights on my Autoroller

I have a Rapido motorhome that annoyingly had a permanent ventilation roof vent directly above the fixed bed, I say annoyingly because every bit of debris finding it's way on the roof ended up on the bed, in addition the wind down mechanism was only on one side and during high winds it would rattle like crazy, usually temporarily fixed with gaffer tape which was hardly ideal, both of these annoyances are now a thing of the past after fitting this roof light.
One other benefit with this roof light is far less light leakage so making for those less than early starts when the sun comes up at 5 am, and I come up at 8 am, so all in all highly recommended, as is Rainbow Conversions for their keen pricing and fast despatch.
