Rated 5 out of 5 by from Great pigment and great size I just received this Eye shadow book in the II Addition.  I LOVE the colors and most (if not all) of the shadows are wonderfully pigmented.  I had an eye shadow book from the regular collection and the books was so big that I ended up taking the shadows out and getting rid of the book.  This one is the perfect size, I can slip it into my purse on the go or I can put it into my train case for safe keeping.The only drawback is the size of some of the shadows, they're really small and it's difficult to get some brushes in.  But other than that I love this product.

Rated 4 out of 5 by from Great Colours in III Addition! I got this in III Addition which I think had the best colour selection. In person the colours are so beautiful. Most of them are satin finish with a few matte shades and like 4 shimmer shades. I'm most excited about the green tones. The only reason this isn't getting 5 stars is because the smaller triangles are so tiny, it's going to be really hard getting a brush into the corners. I like the look but it would be more practical to have square pans.

Rated 5 out of 5 by from Great Pigment The colors are wonderful, and super pigmented. When used with a primer and setting spray I've had the color last 15+hours without smearing, fading, or creasing. The colors in each booklet give you unlimited options. Each square can be used for one look, or they can be mixed and matched. The only downside is each pigment slot is rather small, but for the price it's reasonable.

Rated 5 out of 5 by from TE AMO! I bought it to experiment with different colors and I love it!  They are super pigmented and blend easy. The only downside is some of the containers are too small and it is hard to get a brush inserted!

Rated 4 out of 5 by from Love these I received these for Christmas. I wanted to buy them myself but I just wasn't sure if I wanted to spend the money on them.The pots are extremely hard to get color out of (The 4 small ones on top, bottom, and middle that form the backwards Z...the larger pots on the left and right are fine).The pigments are great and extremely long lasting; however, I ALWAYS use primer and a make-up set spray when I use them.Although the colors aren't all for me, and a few probably won't get used, I love the variety. There are mattes, shimmers, and glitter shadows.

Rated 4 out of 5 by from Good but had cons It is hard to get flat shadow brushes in the small pots on some of the shadows. Other than that great product!<3

Rated 4 out of 5 by from Good Shadows These are good eyeshadows, especially for the price. I've been a designer brand junkie in the past but these are great if you're on a budget yet don't want to sacrifice product quality. These go on easily, are highly pigmented, and do a pretty great job of lasting through an entire workday. I do always use primer, so that might affect the staying power and pigmentation, but I have a feeling these shadows would do well even without primer--they just seem like good quality. My only complaint about this collection as a whole was that there isn't too much variety--mostly just varying shades of brown, which is fine for me, because I mostly go for the neutral eyeshadow look, but not great if you're trying to be creative or just play with your look. Also, I would have liked to see more matte shades--not everyone wants glittery eyeshadow everyday. But, since I got this palette for free as part of the Geo Glam set, I guess I shouldn't complain too much. Just something to consider if you're actually thinking of spending money on this.

Rated 4 out of 5 by from Pretty Good I got this free as part of the Geo Glam eyes kit or whatever it was called. I'm sort of inexperienced as far as eyeshadow goes, but I think this is a nice palette. I do wish there was a little more variety in colors. There seem to be a lot of browns and neutral tones. They are very pigmented and I only need to swipe my brush across them a couple of times. I like that they put related colors close together so that it's easy to layer colors that are coordinated.

Rated 5 out of 5 by from call me shocked seriously I am impressed with elf! I was running late to work today and I saw the elf package at the door on my way out I grabed it and Opened it once work settled down. Im so pleased with the way the shadows go on. Primer is everything a good primer and you can use ANY EYE shadow. I normally use MAC and Twofaced but um they are expensive!! and Elf is my new bestie!
