Outros: Vale apena comprar, muito bom o produto achei que teria uma má qualidade, mas quando peguei pra usar, vi que é muito bom, a Dx.com está de parabéns com seus produtos,... Read more
Rings are great. During the day they change color depending on the mood (but really they change color depending on the temperature of the body :) ). For cons, I can say maybe: In one pack you will find 5 rings with minimal difference in the size. 2 or 3 rings are the same size, half a milimeter is difference... but still it is great :) What impressed ...

Good for teaching the concept of temperature and phosphorescence. The band changes color with temperature and the stars and moons glow in the dark.
Look up phosphorescence and Thermochromism on Wikipedia to learn more. None There are a few in the pack so one will fit and the rest make neat little presents. Interesting gadgets. Good for gifts and as ... Read more
Inexpensive, Glow-in-the-dark Turns your finger green, colors stop working after a month, all 5 of the rings were only 2 different sizes. Good for kids It's a cute mood ring that also glows in the dark and has sparkles in it. The colors are very pretty, but they get big black spots after about a month of wear, and will eventually turn your finger green.... Read more
Nice ring and cheap, they work as expected, it change color by temperature and the moons and stars glow in the dark, it's a plus for the kids, they love it and even old people like me

They work as expected and they're ideal for kids. The colours range from black, yellow, red, orange and so on. They could have more colours, but for the price, they are really good, though. I bought these for my cousins and they loved them! When you put them on the sun, or into the pool, they change colour (as temperature changes). Use your imagination ... Read more
They are fun, well made and quite puzzling. One always want to know which colour it has turned on, but it's difficult to remember what meaning is each colour. I would prefer if they came without moons and stars that glow in the dark.
Don't ever think they'll fit you if you are an adult male. These are sized for little feminine or children fingers :'... Read more
Low cost, fun, suitable for younger girls. My daughter still wears. When a friend has a birthday from my daughter gets nice and inexpensive gift. I have not found any negatives. Perhaps more subtle processing rings, but at that price it's great. I bought four boxes already for daughters classmates. I think I will still buy again. Cheap and nice gift.... Read more
They are nice. There's practically no way they would be defective (= they all work). The materials are solid, the rings don't get deformed nor scraped. They are comfortable to wear. They don't cause any skin colouring. They are really cheap (here in SVK you can buy 1 thermo-sensitive ring for this price of 5 and it's not nice like these ones). The moon ... Read more
