+1 it works for me as well. When using Hex Kit it APPEARS like its not working correctly when using the alignment tool (probably why so many are confused), but it is. Very important to read the text file instructions in the folder.
I Quote: "Select the Pixel Tileset folder. Do not adjust the tile settings, simply click 'Save' on the import tool without adjusting the tiles. The tiles may look like they're outside of the import boundry, but that is because the hex tiles have objects that poke over the hex edge."
And if you have accidentally overwritten the settings that it came downloaded with unwittingly, re-download the folder to fix it.
