This device has a good value for its performance.
I confirmed that the LAMP from this device does send out UVC light and that the safety glasses obstruct UVC light, making use of UVC Dosimeter cards in my video clip. I also have a UVC wand from other shops, and also this unit is much more excellent than both other devices. I suggest this is much better because considering the Dosimeter Test Cards in 100 pcs, anti-UVC google, Silicone Shiels, two shock and dustproof bags and USB cable plus 3 pcs of universal nano sticker in the deluxe Kit. The tilt safety and security is the type of practice, too; I use it to pause the lights briefly while sterilizing without shutting off the system, so I do not need to touch the button to transform it back on.
