Will it be hard to turn on? Someone said it was hard to turn the machine on and off

It is very simple to boot, the product has only one key, long press about 3 seconds to turn on or off;

The product comes with a charging base, 2 batteries, of course it can be charged

Does the product work poorly? Like poor light quality? The effect is not obvious;

We use high quality lamp beads. If you are afraid that the effect is not obvious, we have 3 modes to choose from, and each mode can switch pulses and have a high power in a short time, you can try to feel the obvious effect
