I a happy that you have improved the product. My first Luci which I bought a number of years ago had a solar panel that was affixed to the top of the panel inside the bubble. As time went by the solar panel got loose from the panel and no longer was able to project through the holes properly...that was annoying even though the solar panel was still good. The new Luci now has the solar cells imbedded on the panel which should be a huge improvement. I use it everywhere on hikes as an emergency light when I drive during outages...it's very reliable and I have taken it to foreign countries and used it as a nightlight no worries about batteries outlets just put it under the sun....universal use!!
