"I am more particular about spirit levels than any other tool. I used to be narrow minded and only ever consider Stabila but have/do own/owned Bahco, BMI, Stabila and Stanley. The Stanley FatMax Extreme range of levels is as good if not better than any other level I have/had in terms of both reliability, usability and definately robustness. The vials, handles and coating are much better than the regular 'Stanley Fatmax' range. Is has a thick, sturdy box section, big, clear no-nonsense vials, comfortable, durable well positioned grips, beautiful machined edges and always fulfills its guarantee for accuracy. I use my 1800mm for fence posts, hard landscaping, as a straight edge etc and whenever else I can. It is honestly a joy to use. I own its more expensive Stabila rival the '96-2' in 1200mm and if I had to again I'd buy the equivalent Stanley for less money. Top Tip: Don't whack your level about, it isn't a baseball bat. Good tools taken care of will pay for themselves."
