The product did not do as advertised, and they did not refund the return, even though they said they would. I bought two bird scarer solar spinner motors https://www.outdoorlivinguk.co.uk/solar-powered-spinner-motor.html.
When I fitted them they did not spin. It was a sunny day. I pointed the solar panel directly at the sun and they did nothing. I tried turning the spindle and after releasing the spindle a bit one of them spun weakly when pointed at the sun and not at all otherwise. I sent them back.
Mike Hall said in his defence that you have to point them directly at the sun for them to work. For me that was not acceptable, I don't have time to go out and reset the spinners all day as the sun traverses 180 degrees across the sky from East to West! I might as well be the bird scarer myself!
He would not refund them 100%, so I tried for 50% which he agreed to. He did NOT refund even that. I chased twice in the next month but no avail. I wish I had read the many reviews just like this one for this company before I bought. I hope you do.
