The flashlight is ok for a price 10-15. The flash coverage is really big in the wide-angle. When zooming is the photograph to a 4-square slide projection of the LED emitter. Daszwischen the zoom range, there is a good compromise. The zoom function is not controllable. The build quality is ok but the fit is poor. The touch zoom is so great that the lamp uncontrolled zooms, as soon as you light up the ground in front of him. I've now stuck with Tesaflm and renounce the zoom because my wide angle light anyway like better. It is nice that you can operate the TL optionally with 3x AAA batteries or 1x 18650 battery.
