Edit 6/15/09: I am now more familiar and experienced with stones, so I would like to add a few things. First and foremost, I still believe this is a good stone and at the listed price ($25), it's quite a bargain. I only wish they offered one that was a little wider. I've now tried some King waterstones - the standard for cheap but good Japanese waterstones. In comparison, this stone does not cut as fast as the kings at the 1000 grit level. The 240 side is fairly aggressive and cuts pretty fast, perhaps faster than king's offerings. Like most coarse stones (a notable exception being the bester 500 grit stone), the 240 side dishes quickly. The 1000 grit side dishes comparably at a more moderate pace. More importantly, I feel like this stone leaves a nicer finish than does a king stone at 1000 grit. As such, I recommend this stone in general, but I recommend it very highly if you are on a limited budget and don't want to buy any higher grit stones to finish on. The coarse side is probably one of the better stones in the 240 range on the market, but it is slowed down just a bit by it's narrowness. Neither stone individually is the best of its kind (though you'd have to leave amazon to find some of the best), but taken together and considering the price, it's a good combo stone that could easily be either your only stone or the first two in your progression.
In either case don't waste money on stones sold by knife companies - shun, global, whatever. They charge a huge markup compared to other companies based on brand recognition and people assuming that a company's stone is best for their knives.
However, the absence of instructions in English do make it somewhat challenging since I really don't know what I'm doing.
Also I learned the hard way that rubber gloves are a good idea. As I sharpened my knives small pieces of metal imbedded into my fingers. Not too bad, but a lesson learned.
Packaging and instructions were all in Japanese, but you can find generic instructions by searching the internet. My strategy, in short:
Submerge for 20 minutes
Move the blade in circular strokes with the blade raised the blade to a 10 degree angle
Use the coarse #240 side for totally dull or damaged blades
For cleaning up an existing edge go straight to the medium #1000 side
Keep the surface totally wet, as the slurry of water and ceramic bits is what's doing the sharpening
Aside from needing it totally wet, this stone seems to work pretty much the same as any other sharpening stone.
Although I have never used a pricier waterstone, I don't see much reason to pay more than this one cost. For kitchen use, water is easier to clean up than sharpening oil. If you use it correctly I don't see how this stone would ever clog up or glaze over.
Owned this for a few months. The fine side of the stone was chipped on a corner when it arrived but has mostly held up. A few more chips have come off. If you can, I'd suggest storing this in water all the time rather than repeatedly drying it out between uses. My wife/personal chef remarked that her knives are "noticeably sharper."
It can be used in about 5 - 10 minutes after being soaked in water. However, it takes about a full day to dry completely.
For dull knives:
One side of the stone is 240 grit, which can be used for aggressive sharpening. The other side is 1000 grit, which can be used after the 240 grit sharpening to perform light sharpening. You can then hone the knife on your steel sharpening rod.
For typical knife sharpening maintenance, you can just use the 1000 grit side, followed by some honing on your steel rod.
Note that this stone will not fix damaged knife blades.
My only complaints are that the stone seems a bit narrow. It would be a bit easier to use were it a little wider, like a King Whetstone. Additionally, it seemed fairly easy to score, and I've carved some of the edges off accidentally with my sloppy form-- though I can't compare it to other stones because I've only actually sharpened with this one.
This stone also comes with a rubber holder for the stone that works well to secure the stone on a countertop. That being said, it only works when directly placed on a bare countertop. The first time I used the foot, I spent a half hour cleaning a mess of slurry off my countertop. I've thrown that bit in the garbage. Save yourself the pain, and use a wet rag to secure the stone instead-- it'll collect the slurry and save you the wash-up time.
As a heads-up, the "instructions" are purely in Japanese-- but it makes little difference because there are a number of great instructional videos readily available on the internet.
Without a doubt, this is a great stone for such a low price. You can't really go wrong.

not a bad sharpening stone but not the best I've owned. The fact that you can disconnect the two pieces means you tend to get runover which can affect your end product. Read morePublished 1 day ago by Schahn
