These salt and pepper shakers are ok. According to the description of the product, you should be able to adjust the coarseness of the salt and pepper added to them, but that was not my case. The coarseness adjuster on the set I received is set to one position and there is no way of changing it. The grinders work well, but if you are looking to adjust the coarseness of your salt and/or pepper look for another grinder set.

Convenient Credit Card

This is an effortless and convenient way to purchase Amazon products. Unfortunately I am on it almost daily so the cash back feature is a plus.

The worst banking experience

Stay away from this card if you want to keep your sanity, they had a welcome offer of $750 that they refused to honor, if you call customer service you will be on hold for 2 hours just for them to transfer the call to someone that doesn't know what they're doing. they still ask you to send them documents by mail or fax to prove you're not lying to them. I closed their card less than a month after opening it, the worst banking experience of my life.
