30 Packs Rainbow Hearts Diffraction Glasses Heart Shapes 3D Glasses Special Effect Light for Outdoor Music Party/Bar/Fireworks Displays/Holiday/Club/Lights (30 Pairs)

great! be advised do not work in daylight but once it's dark they are super vivid, beautiful hearts! great as gifts, to bring to events, or just compare spectrum of various light sources (again, they don't do anything in daytime don't be disappointed, they come alive at night)

Love these for festivals

These aren't as good as some other brands I have seen. Other brands, you can see the shapes quite distinctly. These seemed as if they barely tried to create the effect on them. I wanted to give them to my students, but I just tossed them. Waste of money, YMMV.

I got these as an alternative to 3D glasses for a movie night but had much more fun using them on the 4th of July! It turned light fragments into rainbow hearts!! Very cute and made great pics!

It was okay for price but not durable

Look at the lights and see hearts. Call them my love light glasses. That's I I see the world! Lol

There’s are ALWAYS a hit. I bring a ton to music festivals to pass out and heart bomb people

They aren't the fanciest but they work pretty well. They make pin point lights into hearts. We had fun with these while camping. We had fun decorating the plain white ones with permanent marker too. Good for the price.

They technically... barely work if you're staring directly into a laser beam in a pitch black environment.

Very poor quality as the effects needed extremely bright light to create very faint hearts. Almost all you see is the occassional colour change Would not buy again - save your money and skip on this

Die Brillen sitzen annehmbar, der Effekt ist deutlich besser als erwartet und entspricht dem, was man von den Videos im Internet erwartet. Uneingeschränkt empfehlenswert. Die 30 Brillen lassen sich auch super an Rave-begeisterte Freunde verschenken.
