Spectre Hologram Smartphone Hologram Projector Suitable all Smartphones, Holographic Prism

So, its rather small but that's to be expected after looking at the dimensions. It works rather well with my Samsung Galaxy S21 Ultra and looks cool at night or in a dark room with little to no light inside. I don't think you can run into any problems with this thing unless you somehow manage to break it by either stepping on it or leaving it in a bag or something. Probably best to keep it put away safely after using it and trying to not scratch or get the pyramid dirty. The $7 dollars I spent on this wouldn't be something too crazy, but me being too lazy to create my own out of glass or any other transparent crystal like solid or material, I'd definitely say this is somewhat worth it. I don't use it a lot but there's a music app I use that has the spectrogram visualizer with a pyramid display mode which looks cool with the heavy bass music I listen too like EDM and Dubstep. No complaints whatsoever, buy it or make your own, just have fun with it!

works kinda, but not worth the money !

though there are tutorials on how to make your own, it's cumbersome to cut that kind of plastic. This pre-made one is perfect and inexpensive. It's a good way to demonstrate what's essentially pepper's ghost with very little money. Youtube has plenty of videos to demo it's capabilities.

It does what it's supposed to do, but because the quality is so poor the image is blurry and off center. The plastic is so bad it looks 3D printed up close which causes blurriness. The images themselves are off center because it's not made well, and the finish looks greasy with a lot of color distortion. So it's a waste of my time and money that I will return.

I noticed that people were disappointed with the size of this. They don't really give a great representation of it on the product photos and fail to list its measurements in the description (Amazon's description does give a size, but those are never as accurate as those from the manufacturer. I don't know if those listed lower on the page near the weight are for shipping estimates or what, but they are weird.)It sits about 2 inches off the surface of an item. It does fit my Google Pixel XL well. And it works. Is it amazing? Meh, not really, but it is cool. I mean this is an inexpensive novelty item, so I didn't have high expectations. The holograms do show up. You may have to adjust your ambient lighting (it works better in a darker environment) and hold your phone about a eye level to really see it. We have fun with it.I did take a star because mine has a little dent in the edge. Not sure if that was from shipping (it just comes in a ziploc sort of bag, and that bag was in an amazon box.) Also, they really should give customers a little better idea of its size. I will attach a photo of mine so you can see the size.

Works great and is fun. Just don't have extremely high expectations for a product in this price range :) There might be better quality options that are larger for better viewing, but this one works.If you are looking for videos to use with this, here is a playlist that will work (or search for this phrase on your favorite video sharing site "4-face pyramid holographic video"):[...]

A very expensive piece of plastic. It’s not high quality. Might be fun for babies or children.
