So I went and picked up the 10mm ING stones from Yutopia tonight. They are not glossy like white glass stones, but matte like black glass stones. They don't click and clack against each other in the same way glass stones do, and naturally the sound they make against the goban is softer and more like a "thunk" than a "clack". They seem like they will be pretty sturdy, though there is a good chance that the internal weights will shake loose a little over time and be audible inside like tiny rattles. Time will tell.
Overall I like them more than the 8mm glass stones I have, primarily because they are fatter and also because I don't have to be so gentle in handling them.
Here are a couple photos I took with my phone. I hope they are adequate.
I think I must get such stones for carrying around when our Go club meets in that other place (our meetings alternate between two villages 25 km away).

The Ing stones are good for the money. Likes and dislikes are up to the individual user, of course. Some negative impressions I've had:
* The stones are too slippery in my fingers and are easily dropped on the board.
* The stones slide on the board surface too easily.
A cautionary story for Ing stone owners who use them as inexpensive sets to take to the club. I had a set which I kept in the trunk of my car for that purpose. After a relatively short time I discovered that stones were developing cracks and even splitting due, I assumed, to the metal cores expanding when heated.
I hope I don't miss anyone's questions (this forum doesn't seem to have the multi-quote feature, so I'm left to my questionable memory):
1) I live down the street from Yutopia's Santa Monica warehouse, and they agreed to let me pick up the stones there to save on needless shipping cost/time.

2) I didn't need the ING bowls and wasn't interested in spending another $10 for them, so I just went with the plastic bowls. I put the ING stones in my Kitani bowls and put my old glass stones in the plastic bowls.
3) The surface of these stones is not slippery, especially compared to white glass stones. They are comparable in texture to matte black glass stones. I don't fear them slipping from my fingers when placing them, or them sliding around on a goban.
For $25 I think they are a good value, particularly if one takes at least a little care not to abuse them. I think they'll hold up pretty well under most club conditions, and honestly, I'm not sure what sort of stones would endure better under harsh conditions (aka kids).

I've noticed that too, but it may not be true for everyone's fingers, and over time I've gotten used to them. For me, I think it was mostly the larger size I had to get used to, and had to learn to grip the stones harder.
As for the board, you may be recalling the painted Ing boards we've used in Go Congresses for many years. Yes, they are very slippery on those board surfaces. But not so bad on other more natural board surfaces (depending on the type of finish)
I also recently got a new 3cm 3 piece Shin-Kaya board and Korean 9mm glass stones for Christmas. They replace a 1cm plywood board and 7mm plastic stones. Although the old board was pretty mediocre (quite a bit of the lines have rubbed off) I actually liked the stones quite a bit. They didn't feel particularly plastic-like, but the new stones are in an entirely different league.
The heavy, stone-like quality, the smoothness and shine of the white stones, and the perceptibly different feel of the matte black stones and the sound of them clacking on the board make them a joy to play and study with.
A friend asked about the evenness of the stones, and I must say that there is some variance in their shape, and some of them don't lie quite flat, but it doesn't bother me. The old plastic stones actually came with a set of nice bowls. The plastic stones filled the bowls about half way, but with the new stones, about 170 of them fills them to the brim. I'm very happy with them.
