I bought this product because I have a lot of family needing to stay with me for periods of time. Some coming by air and others by car. Keeping up with the sanitizing was driving my wife and I insane. With this product we can simply move it from room to room for 15 minutes at a time knowing that it is completely sanitizing and reaching places and areas we would not be able to or think to go. I don’t want to be one of those people coming behind guests with a wipe and with this lamp I don’t have to. I will definitely buy another so I can do multiple rooms at the same time. Great product!
