Buyer beware - comes without a user guide [SEP] [[VIDEOID:2e4786e03107c573adc8e58602166151]] I would suggest reading the 1, 2 and 3 star reviews. In order for this to work, the door has to shut. This door will not shut. There is no magnet or latch and there’s nothing in the box or unit that is loose. The directions aren’t great. There is no user guide, just a singular sheet of paper.  I took a video to show what I mean.<br /><br />Now we have a defective unit that we have to box up and deal with the return process. What a hassle. I will be looking at other units after we return this one. We won’t be using this seller again. One of the reviews says this isn’t a true UV sterilizer. I have no idea if that’s the case, but wouldn’t surprise me.
