I took a long time to order this because I was not sure what I needed. I do not speak 34;contractor34; and could not make heads or tails of most of the reviews left. I ultimately decided on this one because of the Stanely brand. It does exactly what it's supposed to do. The magnet was strong enough to keep the level in place while I gently adjusted the beam until it was straight. Can't beat the price.
