I imagine this won't give me a chance at £500.00. This must rate as one of the worst products I have purchased, Cheap and nasty components the rawplugs and screws were missing, and you have one chance at fitting on the wall.
If I were the person in charge of the items for sale at wayfair I would remove this item from your range, or risk getting a bad reputation, This item should not be sold at anything more than £30.00.
