Much more reliable than UV torches I own! I do like the design, it’s open on both ends and is wide enough and tall enough to manoeuvre around pieces as needed. It’s lightweight and is powered via a USB cable, making it extremely portable. You can use your laptop to charge this thing. Does not come with the adaptor, luckily most people have adaptors for their phones these days because it plugs into those too. To turn it on, you simply plug it into a power source (there is no off button so you unplug it to turn it off). It’s easy to tell it’s on as there is a moving/blinking red light when plugged in. To turn the light on, there is a single button that switches between 10 second, 30 second and 60 second timers. Pressing it a fourth time will place the light back to idle mode. It’s hands free, which is really nice and makes crafting much quicker. I have found that my UV resin doesn’t always cure under the light, but am 90% sure it’s because I am not curing my pieces long enough. If the light fails you though, direct sunlight will fix any issues… and if it’s still sticky after 10 minutes of direct sunlight, the lamp definitely wouldn’t have made a difference any way.
