Theses ladders are sturdy, both my wife and myself have used them and feel totally safe even standing on the higher steps. Would certainly recommend them even for the more serious of DIY jobs! The pro is the safety catch which ensures the ladders cannot be folded accidentally, the con for me is the steps are deep which is good but a tad narrow for my size 10 plates of meat.... However they still work for me, hence the 5 stars.
Was very pleased with this product - it is of high quality, as stated, and is both strong and durable. It is a bit weighty however, that just adds to the confidence that it instils in you whilst in use.
