This kit was a great idea and easy to use. My only complaint is that about 20 lights didn’t work at all and another 20 were dim. I bought 4 kits, which was 200 luminaries. I bought these for a neighborhood hayride and lined our clubhouse and Main Street. After setting out 200 bags with sand, it was time to drop in the lights. The ones that worked were great and very bright! Looked wonderful. About 20 were dim but if you squeezed them together half would become brighter. I know when ordering lights and small items with batteries you have to account for some that don’t work. Would be a great addition if the company would put in at least 10 extra LED lights in each kit just in case to account for this.The bright LED concept was great; packaging was efficient; delivery was on target(even one day ahead of what was promised) - unfortunately, many (some 50+%) were difficult to turn-on. With some, the tab could be re-inserted, "jimmied around" & the lite would burn. Others, (15%-20%) just would not burn at all. We fortunately only needed some 119 of the bags/lites but instead of having extras out of the 150, we had enough to complete the look we had planned. Another example of where price can sometimes be false economy.The lights worked once you fiddled with them. Which was part of the directions and fortunately we planned for that. Would have liked for it to be easier to turn them off to be able to reuse for the price.Bags were a little smaller than I anticipated, but it was fine.Worked well through light rain and lasted whole night.These were very easy to assemble, and stayed lit over 24 hours.Simply amazing and added so much to the wedding decor, plus I still have the lights to reuse! Great customer service and seller! Buy from them!!!The bags themselves were fine, but the battery-operated lights were horrible. You're supposed to pull a little tab and the light up, but out of the 150 lights that were ordered, there were probably 10 that worked without issue. Most of the lights had to be wiggled and squeezed in hopes that the insides would connect properly and light up. A lot of the lights that eventually lit up had only a small glow rather than a strong light. Most were barely noticeable. Would not recommend this product at all. Our party just looked like we'd haphazardly placed empty white bags around. The lights were a pain to turn on and extremely frustrating!Nice products
