“I can't say I have any complaints about this UV light. It came with the proper adapter for my region and the instruction booklet was simple and to the point. When plugging it in, it does do a loop of the 60 second timer, but a press of any of the other timers stops the looping, and a small piece of masking tape over the sensors has been working well for giving me even more control of the curing time. It looks like the base could be removed, but I see no need to as I just leave it on my desk and use a handheld light for those few items I make that need a little spot curing without being moved. Very happy with my purchase.”
