Many thanks for that ProductReview link, George.
I thought I was going mad or had a specific environmental problem (no units near the kitchen and all away from fans and air conditioners, etc - as per instructions). Now I know it’s not me, it’s them!
I think the obvious issues with the units justify a serious discussion with Quell/Chubb. They’ve been helpful in the past so I’ll pass on that link (which they’ve probably seen!) and ask them very nicely to credit or replace with a more reliable model.
Hopefully CHOICE will add the feedback to their next review.
Cheers.
