Excellent light rainbow spectrum, when sun hits this at an angle.

When the sun shines through there's hardly any rainbow colors like other types of prisms.

Crystal clear and sends a nice rainbow when placed at the correct angle

I set this in a Windows sill and had to rest it on its point, beautiful rainbow.

, It's clear, and makes a bright rainbow on the wall when the sun shines through

Size is nice to be able to hold and see at different angles

The crystal is a great size and weight, and perfectly formed without defects

It is optically clear and a good size for students to be able to handle and to see.

I use it outdoors all the time and it’s a good size too for portability.

Perfect size and a makes a great mirror effect on my images!

Has nice carrying case, good optical quality, but mine came with an air bubble in one end that eliminates the possibility of shooting photos ALONG the prism

Feels solid, looks high-quality, and comes in a nice protective case.

Shipping was fast and it came in a great case to keep it safe when not in use.

Comes with a cool case that should make it easy for transport!

This was well packaged and came with a great storage case.

Good quality, but it didn't work in the science experiment.

Cheap Price and good quality, what else would you expect

This thing was lots of fun and is such good quality that it really separates the colors.

Works great, good quality, and it's inexpensive enough that you can justify purchasing it for a simple conversation piece

The quality and value for money is good but the product doesn't really work

Was here before estimated arrival, just as described it is a perfect glass rectangular prism and is flawless

This Optical glass is fantastic for not only photography but videography

Very clear glass with excellent refraction in sunlight.

No finger marks and broken glass

the glass is very clean , it may be "optical" but its NOT suited for photography, the corners are cut and produce a line , it can be seen in the product picture but i missed it

In turn, if you want convincing effects that will up the quality of your photos and videos, you can't go wrong with purchasing this crystal.

I loved it this is a very nice and high quality Crystal a great addition to my collection

Crystal clear and sturdy. Be careful not to bang or drop as it might chip.

Crystal clear and sends a nice rainbow when placed at the correct angle

Still a cool crystal and all, just not giving the effect I wanted.

It came in a beautiful box and was not scratched or chipped

Thank you for the great service, it came with a very lovely box.

Unfortunately, the box that the prism sits in was completely damaged

The box will open and your prism will fall out .

This came in a nice box and was used for a physics class this summer

There were no issues at all with the product....perfect condition.

The prism itself arrived in great condition in a storage box.

There were no issues at all with the product....perfect condition.

came in a very nice box wonderful condition beautiful color plan on buying more

The prism got shipped and received fast in perfect condition

The prism however, give an amazing twist to my photography.

I recommend using this prism with a lens other than a wide angle lens cuz it doesn’t work as well as a 50 mm

What I got was a crystal clear, beautiful, heavy, full bodied prism

Nice prism, kids have fun making rainbows and shining lasers through it.

Unfortunately the prism arrived with some pretty big chunks broken off the corners.

Slow swipe in front of the lens can create a new effect each time.

Using a prism in front of your lens can really make for some cool effects !

Hard to use but that’s from user error, you get some cool effects with

I use this crystal for photography purposes and I love the effect it adds to my pictures

Perfect size and a makes a great mirror effect on my images!

Product is really good the only flaw I have is the case it comes in with the product

Or, just some kind of sick, "Look at how that rat in a cage reacts to this totally bogus product

I'm not sure if i want to take a chance on this prism again, unless the maker can guarantee shipment of a 100% clear product.

great product, sturdiness marked at 3 because product is by nature delicate.

Awesome product to use with photography juxtaposition type shots!

" Amlong Crystal® Optical Glass Triangular Prism is just an odd thing that I wanted in my collection

Probably the best thing I have bought to improve my photos

Got to teach my kid how to "break" light and learn cool things

A cooler thing to do is to look through the prism at an angle

But the really cool thing I am obsessed by is when you look through it

Nice price for the size

Cheap Price and good quality, what else would you expect

GREAT PRICE

and it's a reasonable price

It was a great price, too!
