[EX Q]: It typically works for a few turns and then nothing comes out after that. I would shake it to try to get peppercorns to feed but that never really helped much. Only emptying it, clearing the neck and reloading it would get it working again for a few more turns. Seems like the neck is too narrow and gets clogged inside. I finally tossed it out because even the disposable McCormick pepper grinder works consistently without all the fuss.
[EX A]: negative

[EX Q]: Shipped out on time and arrived early! Very neat package and perfect invoice/product. Product package was sealed and when opened, product was fresh. Good Quality product!!
[EX A]: positive

[EX Q]: This thing....doesn't suck. It wouldn't even pick a cobweb off the wall. It won't pick up dog hair off of linoleum. Sent it back had a refund immediately. Read the other reviews and belive me they are right! Super disappointed.
[EX A]:
negative
