I must say that my first delivery was a mistake. The light has permanently 'flashed' at power - on, off, but I've now a free return and replacement to get out .... Since then I am satisfied. We see of course that the processing and the material are not sher quality - but it does the job and works flawlessly and has been now 1.5 years. When I read some reviews here, I certainly hope that I will continue to have no problems with it.
