These are super easy to assemble, and look great hanging up around my front porch. They are bright and look fantastic stretched across our awning. Minus 1 star as: The wind can be brutal on these incredibly light plastic luminary bags during winter weather and I had to purchase some equally expensive carabiner type hooks to use rather than nails - as nails will not keep them up, staples would but I didn’t have a staple gun. We’ve gotten lots of compliments and they are so bright and visible we are highly pleased with their appearance. It took 30 mins to assemble - 15 mins to assemble the plastic boxes (fold and fold again as they arrive flat), then another 10 to remove all the plastic from each and every bulb - then 5 mins to plug bulb into the hole and screw from inside the ‘bag’ for hanging.My negative is: so lightweight they fly all over and require a serious attachment and due to their size and airborne condition with wind it bangs on the house/roof in the wind creating quite a bit of noise.Overall very happy with its ease of assembly, and hopeful the standard size bulb is likely easy to replace if ever needed too. Yet too lightweight and could get pricey to weigh down or properly attach and hang for the cost.these are pretty nice. Only thing I'd offer - I wish the spike which holds them down had a loop on top to pull them up again....So far so good! We got one string last year (which was sufficient to go around our small yard), and bought 3 more this year after we moved and had a longer walkway to cover. We had a thunderstorm with 70+ mph wind and tornados go through in December. I had put a few rocks from our landscaping into each bag prior to the storm, and not a single bag moved (they were also staked into the ground using the provided stakes). They don’t look super durable, but I honestly think that the more flexible construction makes them less susceptible to weather damage. One light on the original string burned out right away this year, but the rest are still going strong (we run them about 5-6 hours/day and have had them up about a month).The product was exactly as advertised. The only real issue we had was when it came to inserting the bulbs into the vinyl luminaries. A few of the luminaries received small tears in the back from the pressure needed to insert the bulbs. Other than that, they look great lining our driveway!I think at least 2-3 cords for yard. A good idea is to try different more color lights.The only thing I can think to change would be to add plastic bags to hold sand. The luminarias are not wind resistant and will fall over. I filled quart-size baggies with sand and laid them in the bottom of the luminaria and that keeps them upright. They assemble/disassemble quickly so they can be stored with minimal space. If I could find LED bulbs that would make it much better.These took a minute to assemble, but once they're in the ground they really give a wonderful holiday glow and are very sturdy in any winds.Expensive for what it is, but did meet my needs.
