I reallly have to run out the door but I am shocked you didnt get any better advice. One thing I can assure you is, you get what you pay for. The saying has held true for as long as I have been on this earth. The grinder in the image you have posted wouldnt last me 2 months. The quality of a 9 dollar product is not going to compare to that of a 80 dollar product. Without any hands on with the exact item you have linked to all I can say is this. Look down into the unit and notice the studs/pegs, in the picture you have linked to these are small and THIN. Now compare that to of any other preimium grinder design. I wish I could add more at this moment but I am late as hell to work.

PEACE
