This level is great for leveling my trailer when I get to a campsite. The only thing is the bubble sticks a bit so you have to either tap or tilt it aggressively and then reset it back down on the item to be leveled. The first time I used it, we were a bit off level and as we worked on leveling our trailer I could feel the trailer and see the trailer tilting but the bubble never moved. After I tilted it 90 degrees and back, then the bubble showed its true level state which was too much in the other direction so every time you make an adjustment, tilt your level and then put it back down to let the bubble settle into its true position. If you do this, then the level works just fine.
