What's the difference between this and a Lansky Diamond Deluxe? More expensive for a lesser quality stone?

Blaze9131Lansky's design has multiple issues and limitations starting with limited angle and slop in the guide rod.
Lots of bullet points on http://vipersharp.com about why it's better.

Blaze9131I own the Lansky set with diamond stones as well as their finer grit stones that I ordered separately. As Mike pointed out, one of the setbacks is the limited angles. You can't adjust to the specific angle you would like and this is problematic when either the blade is not very wide or too wide. Blade width will affect the sharpening angle, so the 20 degree hole won't actually be 20 degrees on your blade edge. You can think of it as a triangle between the base, sharpening rod, and the blade. If the blade width changes (one side of the triangle), that angle changes as well.
The other problem he pointed out is the size and shape of the holes for sharpening. The holes are larger than the guide rod to allow for movement in all directions but this can create an un-even blade edge. To get a good edge you need a constant and consistent pressure near the edge of the stone without putting a lot of weight on the left or right of the stone. Too much pressure to either side will have your stone's edge cutting into the material more than the flat side and will keep you from getting the best edge on your knife. This also makes sharpening the tip of the blade difficult since you need to keep the stone flat against the blade while part of it is going off the edge (have to keep the side near the tip from rolling and dulling the tip). Additionally, the rods used are not super strong and can be bent fairly easily. This is also why I mention weight near the end of the stone past the blade edge since weight nearer the back of the blade could cause the rod to bend slightly, making the stone leave contact with the very edge of the blade. You probably wont irreversibly bend them in use since you would have to be sharpening pretty hard to do so but I can see it happening accidentally outside of its container.
Considering these things, I have been able to sharpen my knives well enough to shave my arm hair and the finer hairs near the end of my hand. I also use only 1 out of the 3 rods to eliminate the possibility of slight differences between them since they are not perfectly straight. It may sound like a pain to deal with but if you do not have the time or patience to learn free-hand sharpening on normal stones then this is considerably easier/less time consuming.
I've sharpened 2 S35vn and 1 VG-10 knife with the lansky set using a couple cheap kitchen/folding knives as practice.
