Highly recommended 👍I've been extremely happy with the Tra motorised, rain-sensing roof vents I put on my caravan to replace the quickly perishing originals. They are lasting well, having been in the WA sun for about 5 years now. The convenience of both the rain sensing feature and remote control is unbelievable. I can air out the van from my balcony, with protection should I forget to close them. Seriously... you'd never go back to manual vents.Unfortunately I'd disconnectedly the battery and left a vent open just before a storm went through. The vents were flooded, and whilst I could resuscitate one of the control boards, the other was permanently damaged from being immersed. I thought I'd be lucky to be able to even get a part... for any amount of money... and was sure I'd be buying a whole new vent. However instead I received first-class product support, with a new PCB in the mail the next day, at a price no one could ever complain about.Impressed to say the least.
