Cute but…
Color: White, Color: White
I think this is really cute and a good weight. I expected it to be bigger but it’s about the size of squirrel. The product itself was packaged well and arrived with no damage and had some charge to it already that I was able to test it out right away. It has three small lights that light up a warm yellow but are strong enough to highlight the angel. It has a solar strip on the side of it. It’s a very pretty design but one of the first things I noticed was the angels head was dipped so low that I couldn’t see her face without picking up the statue and looking at it or squatting down to get eye level with it.it would have to be displayed on a higher area or an inclined area to get the full effect of its design. I think the price listed is high for the size and material of the product. I would pay $15-18 for this. If the design was larger and the head was lifted up a bit then I would pay the list price of $27.

Beautiful Solar Angel Garden Statue
I honestly teared up a little when I opened this because it’s even more beautiful in person than I expected from the listing. The angel design with the birds perched across the arms is peaceful and eye catching, and once it’s placed in the garden it really becomes a focal point. I positioned mine in a sunny spot and surrounded the base with a few decorative stones to help hold it in place since the statue itself is fairly lightweight. The solar feature works great, I’ve had it outside charging during the day and the birds automatically glow at night with a soft warm light that looks really pretty once the sun goes down. It gives off a calm, cozy glow that makes the yard feel really inviting in the evenings. The resin construction seems durable for outdoor use and overall the detail is really nice for the price point, though if you look very closely you can see a little bit of glue around the birds. Once it’s set up outside though, those little details fade away and the overall effect is just beautiful. Overall I’m really impressed with this piece and it’s a lovely addition to the garden.
