For the price it’s not bad it’s a little on the smaller side then what I expected I thought it was going to be like with a digital pad on the front like in the pictures but it works well from what I can tell

 

I am extremely new to growing and my first round i used the bag method. I did my daily burp and mist and noticed a small area that was turning a strange shade of almost blue like color. I of course panicked and said F'it!!! Theyre ruined lets throw them out. My wife, the more calm and rational side of me rrad a few things and we were able to solve the problem, but nit without sacrificing a very small part of our yield. However im still very new but am on my 4th go now. The UV pen stays charged and ready for action. We used it on another batch that had a small spot that looked questionable. Within 25 hours everything looked normal again. UV pen a must have!!!

This is a tiny but powerful device. The UV c light it casts is perfect to resterilize areas that would usually make me second guess about whether I had gotten things 100% sterile. If it's even a second thought in my mind, then I hover the light directly on the spot for as long as I want, until I feel it is definitely germ and bacteria free. Just extra peice of mind. Wish it was bigger for the price but still a great buy and easy traveling as it fits in my pocket, hardly noticeable.

Works great! Good price

Nice way to disinfect grow boxes. Not everything is always sterile. Rechargeable
