This is such a great device and it’s so easy to use. Lightweight and portable, great for traveling and on the go. Sanitize anything, cell phones, keys, cards, computers, bathrooms, public tables and seats, hotel room surfaces, kitchens, and the list goes on. Just hold 1/2 inch above surface for 20-30 seconds and that’s it. The only downside is it only runs on batteries or USB cable, it would of been nice to have a rechargeable device.
