Works flawlessly, so am satisfied. What I, however, am not satisfied, is the lack of instructions. Have equal 2 disinfectors ordered, but not a single instruction manual was there! But it is important to know whether and how to replace the UV lamp in case of defect. Designation etc .. That should be it by default but this! The operation can also be explained so by itself, but the rest ... At request the seller could say anything specific for UV lamp. Too Bad ... Nevertheless Keep everything and hope it lasts a long time.
