not bad but the lighting system needs help [SEP] my old eyes are in need of a bit of help at close range for hobby work i bought one of these about two years ago for a lot less money btw and the magnifying lenses do a pretty good job the class act in these devices use glass lenses these are plastic scratch easily and are of fair optical qualitymy biggest gripe is the lighting system two old tech incandescent bulbs which are poorly focused on the work the lights focus does not coincide with any combination of the lenses even worse the lights are not aimable they resolutely point straight ahead illuminating on either side of where i am looking not on the object itselfif you are serious about close work spend the extra money and get something with glass lenses optivisor comes to mind and buy a clip on led light or one of the dedicated light kitsdave
