Detailed small standing angel with light up cross
Color: White
Only a foot tall, so she's a small angel. She would go well on a grave or in a garden. The cross lights up at night. She has an overall nice design, very detailed.

Beautiful angel statue
Size: 7*5*13 in, Size: 7*5*13 in
Got this angel garden statue about three weeks ago to put in our backyard and we really like how it looks. The resin construction is detailed and well-made, depicting an angel with spread wings and three-dimensional flowers adorning the hair, collar, and skirt hem. The craftsmanship is impressive for the price, gives off a soft romantic vibe. The solar panel on the back charges during the day - they claim 8 hours for a full charge which seems about right with good sun exposure. As night falls, the string lights embedded in the flowers turn on automatically which is convenient. However, the lights are not very bright at all. They emit a warm glow but it’s pretty dim, more of a subtle accent rather than actual illumination. You can see the flowers lit up but it’s not going to light up your garden or anything. The soft tranquil glow they advertise is accurate - it’s definitely tranquil because it’s so faint. Despite the dim lighting, we still like the overall appearance and ambiance it creates. The angel design is elegant and the natural elements blend nicely with our garden decor. The statue is weather-resistant and has held up fine through rain and sun exposure so far. The automatic on/off feature works reliably with the solar sensor. The energy efficiency is good since it’s completely solar powered with no wiring needed. Setup was easy, just stake it in the ground where it gets sunlight. The symbolism of angels and flowers is nice for memorial or decorative purposes. The size is decent, not huge but noticeable in the garden. The resin material feels durable. Would make a thoughtful gift for someone who appreciates garden decorations. Price seems reasonable for what you get. Would I recommend it? Yeah if you want a decorative angel statue with subtle accent lighting, just don’t expect bright illumination at night.​​​​​​​​​​​​​​​​

Very nice resin sculpture but LED distracting
Size: 7*5*13 in, Size: 7*5*13 in
I was pleasantly surprised at the quality of this resin Angel statue. It looks better, in person, than shown in pictures. The features of the face, and wings, are very nice. What I found distracting/detracting from my overall favorable opinion is that the LED lights are embedded in the flowers at the waist and base. This is distracting at night as they do not illuminate the face or wings but leaves that in darkness with just bright lights around the waist and base. If the lights were higher up, or more directional, perhaps embedded in the wings to light up the face, torso and wings it would be so much better. To use the solar lights at night, care should be taken to ensure the back is directed toward light and that nothing surrounds the statue to block proper charging, The solar panel in back is very small and will not provide much recharging unless in direct light. If placed on the ground, with plants around it, the panel will be shaded which is not efficient. I am very pleased with the actual sculpture and would rate it higher but, I personally find the addition of the solar lights is superfluous, with no real additional value to an otherwise very nice sculpture. As a result, I intend to turn off the solar light and illuminate this with a garden light/spot.

Great Value, Lasts All Night
Size: 7*5*13 in
Impressed with the quality and performance. The angel is sturdy and weather-resistant. The solar panel charges efficiently even on partly cloudy days, and the LED light stays on from dusk until morning. It provides a lovely, gentle light that’s both decorative and functional. Excellent purchase for the price!

Bright, Versatile, and Easy to Use!
Color: Warm White
This Dual-Power Patio Umbrella Light is exactly what I needed for evening gatherings! I love that it works with both rechargeable and regular batteries—super convenient. The three lighting modes are perfect for setting the mood, whether it’s a dinner party or just relaxing outside. It clips easily onto the umbrella pole and stays secure. Great for patios and even camping. Definitely worth it!
