Eric King you are a bloody legend! 

I have spent months agonising over purchasing a ladder to use on our tree filled property and cut our very difficult hedge which is 5m high and borders a very steep driveway. I have researched and trialed many ladders but none were satisfactory. I just didn't feel safe! I admit I was a bit sceptical that yours would do the trick, but its ingenious design and adjustable foot meant that it handled my requirements with ease. It is also much lighter and easier to use than the other options. 
Good on you Eric, Everyone should have one of your ladders.
