After a few gerbrauch in rough conditions weeks I have ausprechen me absolutely positive. The stick is a flash, nice to look at and has a lot of memory. Had noticed that the stick inside and pull out the plug goes along, making me only close a defect. But now found that the inner life is probably stored in on a rubber accommodate vibrations and other forces. The only shortcoming is probably its length. If the stick is only half as long as it would be 5 star. Maybe soon;)
