I use the little giant pro ( look on u tube )I wouldnt be without mine now, had it about 18 months use it all the time for garage roof access, con roof cleans stradling gates etc.It is exspensive at £200 but its easy to use & stable, alot better than the tele ladders on ebay.
Yea not worth my life Just viewed on YouTube xtend and climb set they look ok, got hydraulic chambers within them for soft close down action..
i like the look of steve aingers one
i have a tele ladder,the type surveys use to get in and out of lofts,ok in the summer but noticed out side in the cold it can start to jam and get stiffi like the look of steve aingers one may get it next year when i sell some work
