Keeps the critters at bay. *by M***G on Reviewed in the United States on October 27, 2022* Ive tested this thing 2 different ways and it really works. Just so, i purchased a second one for if it fails. You cant find another that works this well for the price. A steripen dont work as well as this one does. Charging doesnt take long. And the battery last for for more than a week for me. I use everyday several times a day. Hasnt failed yet after several months! I mix my own drinks with a drinkmate machine and i use this before every liter bottle i mix up. I dont review much but i have to for this. Im glad i bought it. I especially to use on city water after its filtered. No critters in my water. I use it to sanitise phone, computer keyboard, and anything thats comes to mind. Not a germ nut but it paid for itself several times over. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great, easy to use *by S***R on Reviewed in the United States on March 16, 2023* I purchased this for a 3-week trip to India. It was easy to figure out (only read the directions once) and easy to use. It comes in a nice little travel bag. I charged it at the beginning of my trip, and while I didn't use it every day it still help its charge until I got home. This would work super well for traveling too. ### ⭐⭐⭐⭐ 4.0 out of 5 stars I’m enjoying this product so far *by G***D on Reviewed in the United States on January 13, 2023* I have a video on social media.
