Love the Warm Glow!
Color: Warm White
This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

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.

Doggo approved!
Puppy said, "Yes, please." She's a large breed and chews through some toys like nothing. It is May now, and this one is still standing strong. It doesn't have any pieces coming off, so it's quite hard and safe, nothing is coming off for her to eat. It is really resistant to chewing from a Great Pyrenees, and for the price you can't beat it, as it will last months.

Dog tested, dog approved
This is a large, heavy-duty bone. And a great one. My Pitt-mix is very tough on things and can destroy most chew toys in short order. This actually has held up very well to his best attempts. As shown in the picture, after a lot of use over several weeks the most that he's been able to do is to put some small bite marks in it. I'm impressed. That's largely due to the material used. It's a dense, rubbery-type material that's resilient to biting/cutting/tearing. Very solid without being hard. Kind of along the same lines as that used for the popular Chuck-It toys if you're familiar with those (but heavier). I like this softer material better than the nylon bones which he loves but I'm afraid are going to crack a tooth at some point. Has some scent to it but does not have a strong smell. Can't vouch for the flavor but he seems to enjoy it. Again this is large and heavy toy. Probably a little too big/heavy for smaller dogs under say 40lbs or so. Some probably could do it but really better for the bigger dogs. Given how long this one looks like it's going to last, I'd say that it's a very good value. Bottom line - Dog likes it. I like it. Everybody's happy. Great bone. Buy it.
