Review on Combination Whetstone Sharpening Waterstone T0914W by Heather May

I have stored this stone in water with all my regular natural (as opposed to ornamental) stones. One day I noticed that when sharpening this stone was deformed and wobbled. I haven't held the stone in water since then. Now I see a 2 inch circular discoloration in the center of the stone that appears to be gouged or damaged in the center. The stone's grain center has changed, becoming softer and incompatible with the rest of the stone. I straighten my stones before each use and this stone no longer appears straight or flat. This is a good stone but the 3000 grit is quite soft which means it has a short lifespan. store the stone in water but there was no warning about this I will change my review if it's my fault and update if necessary.
