I own about 8 different bottles of this line including some limited edition shades. They are all relatively good they last a good week and a half if you're constantly washing your hands and doing some some heavy duty work. Pastels tend to chip a lot easier, every three days most likely

but there's one bottle in the bunch that I absolutely am disappointed at in the shade Vibrant Violet :( it was one of the limited edition shades of Summer 2012, this is absolutely terrible to apply. This came out as a watercolor purple, and it's absolutely streaky when it's finished! I was disappointed because I really like the shade but I can't return it so it's going to the garbage. Thumbs down.

UPDATE: I BOUGHT 3 MORE COLOURS CAUSE I LOVE THIS NAIL POLISH SO MUCH!!
I purchased the colours Violet and Bubble gum pink (bubble gum pink is almost identical to maybelline color shows pink chiffon) they were on clearance at Walmart for $2.77. Shoppers drugmart sells this like for around $4.50, im not sure how much they go for regularly at Walmart. But either way still inexpensive. I'm quite happy with them unlike most Sally Hansen products that I find extremely disappointing. The colours are very pigmented and have great shine. They do take somtime to dry but the end result is worth it. Plus they do last which is nice cause I have huge issues with nail polish. Even the most expensive ones chip on me within a day or two. So happy to have bought these.

Pros:
-Pretty colors :)
-Glossy finish
-SUPER CHEAP

Cons:
-Chips easily

I bought a few bottles of this since it was super cheap ($3 each and BOGO 50% off!)
I just applied Coral Reef today and the color is very bright and bold - perfect for spring - BUT it was difficult to get the polish to apply evenly. On the bright side, I only used 2 coats and the color is opaque.
I'll probably buy more since these are so cheap, but they're definitely not the best nail polishes.

In terms of nail polish, I love everything about the Xtreme Wear line: cheap, accessible, good quality, long lasting (even survives storage well in my experience without separating), and there's lots of fun, bright colors! Whenever I need a polish pick me up at CVS, I go to this line first! If you're into nude, natural colors, this line doesn't offer much: for those, I'll check out wet-n-wild, or Sinful Colors at Walgreens.

non-streaky! shiny finish. only issue i have is that it chips after 2-3 days.

ive used so many of these before. the colour goes on very well the first couple of times you use it but i find that it gets sticky and gooey really fast. also they chip really quickly, sometimes the whole polish comes off. but its cheap and the colours are pretty

This line of nail polish lasts longer than anything, for me. I have many colors and they are all great and long-wearing. I used them with Orly Bonder basecoat and Revlon Extra Life topcoat. I like the brush better than OPI, I find the OPI one to be too wide for me.

*This is a review for the "lacey lilac" color*

I didn't really like this polish. The color goes on clumpy & kinda skips patches in my nails, and yes I use a base coat. I think I either got a bad bottle or it's the way that this color is formulated because I love most other Xtreme wear polishes. The only reason I haven't thrown it away is because the color is so pretty. continued >>

I got the sparkly red colour because I was looking for a sparkly red nail polish and this one fit the bill perfectly. I quite like it - it went on well, dried reasonably quickly, and has good coverage. I did two coats but you could get away with one if you were in a hurry. And the price is right. I give it 4 out of 5 stars because it doesn't dry rock hard as fast as I'd like - I dinged my thumb the morning after I applied the nail polish when I scraped it against a concrete wall. So not exactly a failure but not ideal - I should have seen a scuff, not a gouge.

I also really love that it doesn't shrink when it dries! No bare tips! Yay!

Update: just wanted to update y'all on durability. It's about average (not Xtreme by any means). It doesn't last as long without chipping at OPI or China Glaze. It's the type of polish you have to be careful with (I ended up doing a lot of sorting and archiving and inventory at work and chipped a couple fingers) and touch up every couple days. But I'm not knocking off a star because I love the colour so much, and the chipping is fairly minor and easily touched up.
