Looks like you are searching for coffee gear on Evilbay..... which most of us believe is not a good idea..... that "bargain" you find on Evilbay will more often than not turn into heartbreak city.
Although the grinder is advertised as "new" it doesnt have any warranty - which should ring alarm bells....
It is a small conical grinder.... so I suspect it is similar to an Iberital Challange.... but have no knowledge of the brand... and a doubt the claim "semi-professional". Spare burrs would also be a problem.
It might be OK - but you are taking a huge risk with this sort of gear.... no warranty and no ongoing support....... Id approach a site sponsor.... or at least someone you can go back to if things go pear shaped after purchase.
