solid, great quality - I will say; the little note with it really did not help in getting it to work, the words made no sense and the image was too blurry... I thought I had bought a dud... Then I twisted it differently together and it started working... THEN, when I looked at the image I kinda got what it meant... but would recommend instructions for people like me who have never seen one before. Service was fantastic and the order arrived super quickly. Also really appreciate the refund on overpaid shipping, without me even having to ask for it. Thank you very much for that!
