Glow Roxx - 100 Pcs (Blue) of Glow in the Dark Rocks Perfect Accent Pebbles for your Driveway, Pathway, Wedding Favors and Decorative Fairy Garden

edit: I uploaded a number of images but I'm only seeing one right now. Will edit the wording of this review if they don't come upShort and to the point: the rocks can glow beautifully if given enough light, but if you live in an area with ambient light they'll be far less noticeable. I do not believe this to be a fault in the product but the nature of glow-in-the-dark-products and the human eye. Unless you live in the country far away from street lamps I wouldn't expect anything like the product photo. If you're looking for interesting fish tank decor be warned some of these rocks contain tiny air bubbles and will stand on end, but with 100 rocks you've got plenty to swap out with.Now for the detailed review:Any photos I've taken were using my cellphone. I do this because if I use my DSLR and take a long exposure in a dark place these rocks will seem to be far brighter than they are in reality, so please bear with me on the image quality in the dark.The rocks are slightly larger than a penny, as I've included with my review images. Right out of the package I decided to shine my phone's light on it and even with the light of the sun and indoor bulbs I could very plainly see the bright blue glow! I set one of the rocks on an LED flashlight for exactly two minutes in an effort to test how long it would hold the glow. I had initially set a timer and left the rock in my closet but, four hours later, came to realize it wasn't necessary. The rock was still glowing. I took the rock into my bedroom after dark to see just how long it would take for the glow to stop. The last time I remember checking on it was about 3am and it still had a visible glow to it- so it was going on for many hours. Definitely can hold some light! You'll see the results of this next to the penny out of the bag as well as in the image for the next section.The next test I decided to do was to see A.) how hard it would be to break one of these rocks and B.) to see if it still functioned after destroying it. Now, I enjoy smashing things with a hammer as much as the next guy, but these rocks did not make it easy for me. The hammer would repeatedly bounce off and the rocks with no damage done and the rock would skid to the side and ricochet around the garage, so I'd say they're very durable. However, I'm a persistent person and after putting it in a bag and securing it with a vice I was eventually able to start the long process of smashing it up. If you're looking to make these into little fragments to turn your bag of 100 into 1000 you're in for a VERY rough journey. Hopefully these guys will produce a smaller, more numerous variety to save you the hassle. Anyway, it turns out they glow just as well after being broken up! Again, held an LED light over these for a few minutes then took a picture in the complete blackness of my garage. You'll see the attached photo.Now for the real test: outdoors. I live in Central Florida where the sun is always glaring down. For this test I set one intact pebble on the outer crack of my patio as well as the broken bits from the previous section. I also set the remaining bag outside on the screen. After a full day of sitting in the sun I found the glow wasn't quite as intense as I had seen in my bedroom or in my garage. I gave it a few days but each yielded the same result. I took the rocks into my garage and found they were glowing just as beautifully as when I had used the LED flashlight. So what's the problem? Ambient lighting. I live in a suburb where there are streetlamps just in front of my house. The rocks ARE glowing visibly when sitting on or near the patio but it is not something I can see from a long distance. The photos of the glowing roads and earth you see on the product image are likely the result of a lengthy camera exposure- which is precisely why I used my cellphone to take these pictures instead of my DSLR camera. I wanted to provide you a more accurate depiction of how they look. You can see a more distant view of my patio in one of the pictures and, honestly they don't look too bad even WITH the solar lamps on each corner. If you live somewhere in the country far away from lights you'll probably end up with a very beautiful glow at night. If you live in a suburban area like me I recommend using the rocks in a cluster. I found the bag of rocks stood out more than they do placed individually. Either get a whole lot of them or make sure they're bunched up and can shine together!Now for the fish tank. Similar products to this one all advertise as being aquarium-safe and my fish have been alive and healthy since I popped these in a few weeks ago. After a long day of white LED light they glow very nicely without a light. I must say, though, that if you're like me and got a light with a blue night setting you'll probably want to go for the green rocks. Blue is, unsurprisingly, not standing out very much. The rocks stay put for the most part but I did notice a few of the pebbles refuse to lay down. I think there's some bubbles trapped inside the rocks so you'll want to put a bunch in your sink and pick out the ones you see laying flat. They're surprisingly light and may float around otherwise! I know I've got at least one traveling pebble that needs to be escorted outside.So if you're using these indoors I'd certainly recommend them. Outside, just make sure you're in a dark enough area and don't expect a fairy-tale utopia otherwise. They certainly work!

They don't glow for very long, even after leaving them in the hot hot Mexican sun all day.

I really like these but wish you got more in a bag. I use them in our bird bath & they are pretty. I may go ahead & buy the green as I read they are even brighter. I think they give off a nice glow.

These are the Read Deal! All I can say is WOW...After seeing a driveway full of glow in the dark rocks on Pinterest, I was obsessed with making my front pathway glow like that. The first rocks I bought on amazon were pieces of crap. They barely glowed and the glow didn't last more than an hour or so. I was really disappointed.I found out about these GlowRoxx on pinterest post and gave it one last try with a bag of the blue and a bag of the green. When the rocks arrived I was completely BLOWN AWAY. They even glow in a dimly lighted room, right out of the box with no charging. They glow so bright they make the other rocks I bought before look like regular pebbles. Now that I have found the real ones, I just put in a reorder for another 10 bags of GlowRoxx and I can't wait until they get here. Stay tuned for pictures!

Occasionally I can see a glow from these after being in the sun all day. Keyword "occasionally"

You need more than 100. I should have gotten bout 500 for what I wanted to do. Barely glow!!

you cant see it far away however it does glow when you get closer

Doesn't glow like I thought it would. Not worth sending back.
