It was an alternative, Some people do live near a Wilko and have to drive to a Screwfix.. Different strokes :)
Plus there's no click and collect (normally chargeable) so I guess you would have to ring up & check if in stock, issues parking town centre (in my area). Not worth the hassle, for a lesser product.
Yeah saw that one too, but no Wilko near me and didn't want to wait for delivery. Picked mine up this morning, and us perfect for the pool filter pump. :D

Why freezing temps? 5 metres more cable than this which didn't go cold. Heat from me anyway.
