Material of trident device.

I have several of the 'white' Aneros devices.
Helix classic, Helix trident, HIH 950 and large Peridise all White.
Eupho classic, MGX Trident and small Peridise bone white.

One other observation I'd like to share.
The Trident Helix body is smaller than the Classic Helix. I don't have a micrometer, but the size difference is obvious when compared side by side visually.
And, when held in the hand, I can clearly feel the extra bulk of the Classic's body compared to the Trident's.
I get better results with the Helix Trident.

Hello Lovingwife, I may not be fully understanding your question, but I own both the Eupho Trident, and the Helix Trident. The material used for both is exactly the same, and both are also the same color. When I compare either of them to the classic models, they look a little more dull, and maybe not quite as white. Hope that helps!

If I understand the question, why is one colored bright white while the other is a little more off-white. Are they made of the same material?

I have noticed the difference in the white color of different devices. You described it quite nicely, some being bright white, some bone white. My Eupho Trident is bright white and the Maximus, Helix, and MGX Trident's are the more bone white. All were bought directly from Aneros. The bone white models seem to polish up perfectly, almost "white-ICE" type of finish. I have another model that is bone white but can't remember which one.
