Works great! Delivers on its promise! This is a high quality tool. There is zero flex when spreading peanut butter and zero mess on your hands when using it! Plus, my knuckles are not scraped on the sharp lip of a plastic peanut butter jar. It is a little long but that's what you need to get to the bottom of a big jar from a warehouse club! The round, red handle is comfortable to use when dealing with thick, crunchy peanut butter. The rounded nib at the end is perfect for scraping the last bit out from the bottom and from just under the top of the jar. It's worth it for that one less aggravation in life!
