Don't be under any illusions. I am not, and I wasn't when I bought it, I was just curious. The price was $47.37 with Free shipping. I selected the assortment with 11 stones (none diamond).
The name of the game on AliExpress these days is every kind of game, misrepresentation, and outright lying to sell stuff. This is absolutely no KME and when you get it, it is plainly labeled "Sytools K2 Pro". I'll note that there is a K4 pro also (but I have not investigated details). This is so rampant, I am tempted to -not- blame Sytools and rather whoever is doing the listings on AliExpress.
All that said, this is a pretty nice unit (but I'll have more to say after I sharpen a few knives with it.
I'll mention in passing that I have caught wind of another unit on AliExpress that uses the same stone called the Ruixin Pro.
With no stones, you can get the Ruixin for $21.02 which is tempting. No lying nonsense about it being a KME.Just for reference, the stones you get with a real KME are 1x4 inches and you get:
50, 100, 140, 300, 600, 1500I end up ordering a set with 80, 150, 240, 500, 800, and 1000 and 3 single stones besides. Order placed 1-23-2023.
