I shoot a lot of virtual tours with the 303-SPH head and this leveler. The leveler is a real time saver and the perfect compliment to the head. My only gripe is the tightness of the adjusting screws. At times, they are fairly difficult to turn. I thought they would loosen over time, but I've had this product for almost two years. The problem persists. A little WD40 helps, though. This is not a major problem and would not keep me from buying another if I ever need one. This thing is built like a tank, though. So, unless I lose it, I doubt I'll ever need another.

It works well as what it is designed for.

However, to haul this extra wight for a long walk is not as desirable. In fact, Manfrotto's devices are always in the heavier side. It really can be made with lighter (yet stronger) material.
