a downside of the ABRU is they catch the wind like a leaf when you arent on them, i read of a tip to fix a small bungee cord to the top with a crocodile clip on the end to fix to the gutter or sill maybe
i know the ABRUs look rubbish,clank as if made like an old bean tin but theres something about them .
on reading Abrus own website, they do an even lighter "target "range ,for the homeowner . the ones on sale in BnQ are the "professional " range , though i agree they look cheap, ive given mine a lot of punishment and no worries
