I purchased both the regular size and the jumbo 2 ounce size in based primer. I felt that they both had different consistencies. The regular primer, which I love, is very silky and velvety to the touch. It tries beautifully on the skin and makes a very nice even surface to apply foundation and makeup. The jumbo 2 ounce primer was much more runny, liquidy, and watery then the original size. I shook it up a lot and I continue to shake it up each time I use the jumbo primer. I purchased the jumbo size because I thought it was a great deal since I knew I loved the regular size and knew I would be using this every single day. I absolutely loved the original size when I bought it and tried it for months. I was pretty disappointed that the jumbo size primer has a different consistency than the regular size. Also I have noticed when I apply it to my face it is not as velvety of a finish. I also wished that the year there where more product images of the packaging/bottle in both sizes. The original size is in a pump. The jumbo tube is a squeeze tube, Think of it as a giant squeeze tube of lip gloss. I don't think I'll be purchasing the jumbo size unless I just received a bad jumbo size tube. Perhaps I should try to exchange it and see if another new one has the same watery issues. Otherwise I will be going back to the regular size pump. The regular size pump gets five stars, while the jumbo tube size gets three stars.
