Item ordered: May 21, shipped May 24, received in Italy May 28. Very good service. Used Super Saver service too. I had a little problem with the item that I was able to fix myself. See photo. The ring (C) that attaches to the bicycle would not slide back into its "shoe" (B) properly and stay in place. I found that by removing the screws (blue lines) that hold the shoe (B) in place, I found two more screws (red lines) on the body (A) of the light that were incorrectly placed. They were supposed to be in the holes (yellow lines) so that they would be countersunk in the holes. After making this adjustment (putting the second set of screws in the correct holes) and putting the "shoe" back in its proper place, I was able to slide the ring assembly into the shoe and also release it using the release button on the shoe assembly (B). Without this adjustment, the ring assembly simply kept sliding out of the shoe. In summary check everything to see that it works properly before you use it. I did put batteries NOT INCLUDED (3 AA Alkaline) in the light unit. All of the lights worked well. There are four modes. 1 ring of lights (LEDs), 2 rings of lights, 3 rings of lights and blinking lights. Hope this helps all you buyers out there.
