I’m thinking of getting a set of extendable ladders for general use around the home. Don’t need them to get on a roof or anything that high but maybe for reaching upper windows etc. Is anyone using them? I don’t like wobbly ladders although I know these must be more 'flexible' than a fixed ladder so when buying, price is not a consideration and although they would be for home use, a real top quality set is what I would be looking for. Any recommendations?
