It feels cheap and works just okay
This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!
Color: Cool White
This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.

Easy to use
I love these. Not only do they work at reducing any blemish size and inflammation, they are practically invisible like advertised.

Really help soothe redness and speed up healing
I've been using these patches for a while now and I'm very happy with them - they're virtually invisible on the skin, stay on well and really help soothe redness and speed up healing.

My kid loves them!
My kid loves these. They also said they like that, unlike some other ones, they can see underneath it somewhat to tell when its more ready to come off.
