Review on SignoraWare Easy Pour Oil and Vinegar Bottle Set - 4 Pack of Olive Oil Dispenser Bottles with Non-Drip Spout, Airtight Lids, and Easy Fill Wide Mouth - Liquid and Dressings Plastic Containers - 2 Bottles of 15 oz and 2 Bottles of 21 oz by Jasmine Grant

UPDATE - Decided to increase the rating. After playing around with it a bit more, I found that the top lifted quite easily if I pressed down on the small lid with my right thumb while pulling it up with my left hand. My butter knife is no longer needed! Otherwise it does a great job. No oil leaks out the side or drips which is why I bought it. I really thought I would like these containers but if I had known then what I know now I would not have bought them. The small caps are too difficult to remove for me to pour out the oil, defeating the purpose I bought them for. I have to use a dull butter knife to remove the small caps. I thought I could loosen them up by closing and opening them a few times, but that didn't help at all. I probably won't send them back. I'll just use them handy with a butter knife, but I'm not keen on it.
