Yes, for the money it is a good setup but make sure that you get a set with the original style clamp and not the one with the rubber inserts.
And.... you can easily make your own diamonds stone / sandpaper / polishing tapes holders. Not only because it is dirt cheap but also because they work better and faster.
I made these from 12x18mm wood, 4mm rod, 5x20mm aluminum strip and 2.5x25mm aluminum strip. Since I use 4mm rod, I can also use these with my KME system.
I use the ones with the 5x20mm with sandpaper and 3M diamond lapping films and the one with the 2.5x25mm strip with double sided diamond stones.
The total cost for the materials for the 5 holders including two double sided diamond stones (150, 400, 600 and 1000 grit) is less than 20.-
Since these are larger than the original Lansky stones, they work a lot faster and so far, the Chinese diamond stones perform a lot better than the original Lansky diamond stones.
You can find the diamond stones on eBay by searching for: Double Side Diamond Plate Ti Titanize Knife Sharpening Stone
I just tape them to the holder which works perfectly.
