Really bright. Love the compact size. Only thing is hard to figure out the settings for alarm and time etc. got the time set but accidentally set an alarm for each day and cannot figure out how to get rid of it and after a week of being annoyed by a random alarm I just pulled the battery. Unfortunately I lost the booklet, so still have it 5 stars as I assume if I had the instructions it wouldn’t be an issue. Fits perfect in my nail supply cart.
