One distinct thing to note is that this is killing the unseen germs, not making your device shiny. I suggest using some form of cleaner to get off all the normal stuff smudges and smears from your devices and then tossing it in. I was easily able to clean Karbonn A30. It leaves a shinny look behind which makes your phone look refresh.

I recommend it! Based on their performance with other sanitizer products, this is worth it!
