The best thing is it does not shine in my eyes! It is so simple with its heavy-duty magnet on the end. The downsize is I am not the best at turning lights off so I will need to keep AA’s on hand. The other is there are three settings: hi, low, and red strobe emergency. To turn off have to have gone through all three. So if on high when using, have to click to low and then again and get a flash of strobes, then off. Not a big deal unless that quick moment of flash bothers you. But it is the best ever to sew by! Finally a remedy where it doesn’t even get in my eyes when face close to machine to thread needle. It was pricey but I don’t care as I am happy, happy, happy. It comes in a box the shape of the light. Brand “NEBO” BIG Larry. Oh, and it does not wobble or shake while treadling.
