Quick Burr grinder question

[pektel]

I see it's not a conical burr grinder. But as of right now, I have NO grinder. When I buy coffee, I have to buy it pre-ground.

Think this is even worth purchasing? Or just keep on with buying preground stuff until I can buy a good conical burr grinder?

Thanks in advance.
