Simply the best low end grinder i used, i tried most all the other popular low end grinders (4 of them), getting the ProLine was a relief ;)
Positive Product Points
Consistent grind, no mess (others burr grinders i used showered the counter top with grinds), nice solid design, well thought out. I notice the collector is glass and curved at the top, one might think for style, i think this what prevents the coffee grounds from flying out, they use the static to keep the grounds in the collector (it seems from all burr grinders they all produce a fair amount of static, i believe just inherent using a burr to grind the coffee).
Negative Product Points
This grinder works great. By trial and error (more error) i now owned and sold or returned all the low-end grinders. While i was first put off spending about 50% more for the Kitchen Aid Pro grinder than i saw some other grinders i have a co-worker who purchased the ProLine. Determined not to get burned yet again, i asked him if he wouldn't mind letting me try out grinder before purchasing the ProLine. I was very happy with the results and purchased one. It will serve you well to search the web for different prices, seem one vendor per month will sell this for about $160.00, and others go up in 10.00 increments. Bottom-line if you want a good solid grinder, i doubt you will not be pleased if you get this grinder. Also in comparison to the other grinders, this one does not make a mess, appears to grind the coffee much faster than other grinders, provided a good consistent grind, and even lets you get more precise grinding increments.
Can't remember the vendor, search the web, i found the cheapest was about $160, but on back order for too long, spent $10.00 more and it was shipped that day.
