Since I but actually worked tadelos I taken them anyway and the concert was great. My grades I could read without problems and you could adjust the brightness was really great.
But you should perhaps somewhat cautious handle it for the price you can not expect a top quality !!
3 points there only because I'm afraid the real turn on the lamp breaks me !! And because the wire inside it is a bit stubborn and I had long tinker around until it seemed as the two Sheet music were well illuminated.
Will be retained for the concert next year in a safe place and she is still wanted their services Tuen awhile. One just needs a little careful.
