Hassle free in every way!
The first one I recieved had a tiny imperfection (a bump in the casting) but Amazon returns are so easy I got a replacement within a couple of days. The plate itself is great and cuts really nicely. I used to use nothing but water stones but having to flatten them all the time becomes a real pain. These dimaond stones are worth the investment and I'll be replacing my last two water stones once I have more funds.

Unbelievable quality.
Great quality! So happy I finally took the plunge and bought one! Now I need to buy in fine/super fine. I already have the wave sharpener in fine and it really does a fantastic job on gouges, so won’t hesitate to buy more when I can afford to.

Lapping stone
Bought this to lap flat my Norton whetstones. Works well on low grit stones but pretty slow cutter on the higher grits i.e 4000 and up. Easy to clean with some cream bathroom cleaner or toothpaste and a bristle brush. Best price for this item I could find online. Did take 6 days to arrive though. Although must add I took standard delivery option.

Very poor quality
Sharpened one large cleaver, flattened one 1000 grit whetstone and it's very much the worse for wear. I expected a lot more longevity at this price point.
