Customer Reviews
Fitted this to the skylight in our new loft conversion. The automatic rain closing feature is an absolute lifesaver given the unpredictable London weather. We can leave it open for ventilation without panicking when we're out.
The 400mm stroke makes a massive difference to the airflow compared to our old manual winder. It pushes the heavy double-glazed vent open effortlessly. Really solid piece of kit.
As someone with mobility issues, reaching the high roof windows was impossible. This remote control window opener has given me my independence back. The installation by my local electrician took less than two hours.
Great electric roof vent opener and it works exactly as described. I've dropped one star just because the wiring diagram in the manual could be slightly larger for older eyes, but once wired in, it's brilliant.
We were quoted an absolute fortune to replace our existing manual windows with electric Velux ones. Bought two of these actuators instead and retrofitted them. Saved thousands and they work flawlessly with the rain sensors.
Using this in a large glass conservatory. The remote range is excellent, easily reaches from the kitchen. The motor is a bit visible on the frame, but it's a small trade-off for not having to climb on a stool to open the vents.
Superb value for money. I was worried it might feel cheap but the stainless steel chain is very robust. Love that it's fully UKCA marked too, which gave my installer peace of mind.
