Charming little solar accent for the garden
This angel statue is absolutely adorable and adds a sweet touch to my front flower bed. The sculpted details are surprisingly refined for such a compact piece, and the solar panel charges well throughout the day to provide a gentle glow at night. The light isn't overly bright, but it creates a lovely ambient effect that's perfect for pathway edges or nestled among plants. The statue is smaller than I initially expected based on the photos, but that actually works in its favor—it's easy to tuck into various spots without overwhelming the space. I've had it outside for a few weeks now through some rain and wind, and it's held up beautifully with no fading or damage to the finish. The solar function has been consistent, lighting up reliably each evening. It's a thoughtful piece that would make a great gift, and the compact size means it works just as well on a small balcony as it does in a larger garden. If you're looking for a subtle, charming accent that requires no wiring or maintenance, this little angel statue is a winner.

Resin
This 8 inch tall resin angel will add the whimsy to your garden. It is solar powered to charge during the day so the butterfly will shine at night. Very durable and waterproof. This angel is very realistic with its wrinkles and dimples. I would recommend this cute little angel, but I feel it is a little overpriced.

Great product! Wish I had found it sooner!
Perfect solution for our umbrella stands! It is slightly taller than original pipe on stand (this is a plus!) Has two bolts instead of one (Another plus) to help secure the umbrella better. Has two rubber reducers to fill in gap around the umbrella pole. Only issue is the shank on the bolt is too long (bolt that secures pipe to base). Extra bolt was too short. We are purchasing another one for another umbrella stand. Great price for the product! And was easy to install, keeps the umbrella straight and upright!

Good quality, but likely holds water.
Good quality and was easy to install on base with two bolt lengths provided. I modifed by drilling a small hole through the base of the pole mount so that water can drain out. I have previously ended up with a rotten wooden umbrella pole because the pole mount held water!
