I love the size, material, and brightness of the light. The button feels nice. I'm a little bummed that it doesn't feature a switch that works the same way as the Reylight Pineapples (push for on/off, tap for brightness adjustment. Defaults to dimmest brightness), but that's the only downside to the light, and the price is outstanding.
jalvanifwiw, you can use the head of a standard Lumintiop copper tool that starts on medium, on the eSwitch body if you prefer MLH., or just buy the standard version and use its tail switch if you want the help press feature. both the heads and tails of the tools can be swapped around.
