As I said - I RELY on the Travelites but take advantage of the Einstein. The Einstein claw mount system is flimsy and is NOT positive locking. But I've used the Einstein on a boom (small and large booms) with soft boxes, reflectors, grids, etc. and it is easy to use, nothing has fallen off. The modelling lamp is always set to 1/2 power, so it does not overheat.
