Swanson Tool Company Aluminum 48-in 3 Vial Magnetic I-beam Level

Unreliable after less than a year

Bought the level when we built a greenhouse. Worked okay for that project, but when we went to install shelves in the home a few months later, found that it wasn't that accurate. The level was bowed in the middle even tho we stored it vertical using the nail slot at either end. Will try and return it for a better one, even if a bit higher in price. The pros are that it is very light in weight and has a 360 degree adjustable vial. But, those are useless if the level itself isn't straight.

Great value

I used it to frame a room addition and it served me well.

Good quality for the money.

Magnet is handy but needs to be kept clean of grit for accuracy.
