I had a little trouble with one of these when I received them. The mechanism was too far inside,
and was extremely difficult to operate without jamming my thumb in super deep. But I contacted
Penguin, and they sent me a new one immediately, and it works perfectly.
I like the lights, and
there's a lot of potential in using two of them. For the price I don't think they can be beat. But
I have to say, Penguin's service has always been exceptional. I'm a huge fan!
