Hi JS
That was my thinking that it’s down to commission but never thought about the time to fit so another probable anwser.
Althought the Autochair is around £100 dearer than the Brid-Ayd now I know the Autochair and this being my first hoist in future I will more than likley stick with AutoChair because it’s the devil I know and can’t fault it but may have been a different story had I’d not got on with it though.
