It does the job... I have oily lids and it keeps my eyshadows looking perfect from dawn til dusk!! it is liquid and really easy to apply..
what I didn't like is that the first time I squeezed it, instead of a creamy-liquidy consistancy, it was an oily kind of liquid. and I understood that it was parted inside the tube.. after some squeezes it turned out be fine..

I suggest you give it a try!! propably I will repurchuse if I don't find anything else..

So far so good with this primer. I still feel like I need to try it out more before I make a full judgement on it, but as of right now I am satisfied.
Here's a bit of a background for me. My eyelids absorb all eyeshadow- I've always had a problem with it. I have tried three eye primers before this one and hated them all (Revlon, Stay Don't Stray, and Gosh). They just made the problem worse, and creased my shadow more.
I have found that this makes my eyeshadows look more vibrant. I haven't worn this for 12+ hours yet, but I've worn it for about 8 and my shadow hasn't faded/creased. I even wore it swimming once, and I came out of the water, looked at my eyes, and my shadow was still on! (It wasn't waterproof shadow either). So, yes I am very satisfied with this so far. If I find it continues to work, I will definitely repurchase.
Another thing I like about this primer is the packaging- the tube makes it very easy to control how much product comes out.

...What is this? My eyeshadow did not transform into anything more beautiful, & the formula is awful. I applied this primer on my eyelids & attempted to blend it in. Nope...It barely budged. TF Shadow Insurance is the driest primer I've found on the market. Typically that would be an incentive to buy it... but with this, it's really just too dry. Even for my super oily skin. I don't want to apply this on my eye area again because it could be damaging to the fragile skin.

If they made a face version of this, that actually blended in properly - I'd be all for it! Until then...I will never repurchase. continued >>

I’ve been using this for a while now and have been impressed every time I used it, but it wasn’t until I brought this to Vegas with me that I was blown away with just how… ‘effective’ it is. I have slightly oily lids and while my other primer that I use for less special occasions works great too, it only works well up to a certain amount of time. But Too Faced Shadow Insurance? No expiration.
I used this while I was in Vegas and I was dancing for almost five hours, sweating profusely, and was almost in a humid environment but my eyeshadow stayed put. It remained looking so flawless before, during, and after the sweaty dancing that you would think I had just put it on. Like seriously, this primer is a life-changer. And it makes my eyeshadow pop. And a little really does go a long way in terms of usage, so I’m pretty sure that a single tube of this will remain forever in your makeup drawer. This is so worth the purchase.

I have sensitive eyes and eyelids and I prefer this primer over the Urban Decay Potion Eye Primer. Both provide the same staying power but unlike the UD primer, this one did not irritate my eyelids.

I bought this primer thinking it would work out great cause of the reviews i read. I put it on in the morning and halfway through the day it creased! A few days later i thought id give it another try and within 3 hours and a half it faded and creased. It was such a disappointment. I prefer my Mary Kay primer

I have tried them all as well...UD PP, Lorac, Lancome (very good btw) TooFaced is up there near the top though just a rung below Lancome and I rate my Dalton Conceal-it a notch up above them all. I am picky. I have been wearing eyeshadow base primer for 15 years before it got "popular" in the last few years. I still think it is crazy to use anything but a silicone based concealer that you can also use for other things. Why spend more money if you don't have to.

I have tried them all, Lorac, UDPP, Nars and this is the best. As it comes in a tube it is the best value, you get more porions of an oz then you do with the tube type like Nars by double. Then the performance is just better, I have used the same shadows with ea of the above and TFSI kept my e/s in place better than all.

It's the first primer I have ever tried n I am hooked..I just don't have the appeal of eye makeup without it. my eye makeup goes on smooth, effortless, no creasing or greasy lids. The eyeshadow colors show up more pretty with it...overall a very good product I must say

I just love this primer. I have been looking for really long time a good primer for my eyelids because they always get oily and my shadows are ruined. I tried Mac's and it was a disappontment. I also tried nyx's, the three shades they offer, and they make better shadows or bases. Also jordana's and even urban decay's but this is by far the best. It seems like it dries and glues the color. Even my cheapest shadow remains intact. I also love the natural color it has. Many primers are too 'white' and noticeable, at least in my medium skin. But this one is natural colored and it's absorved in five seconds. Finally, another advantage is that it lasts ages. Since it's creamy-almost-liquid you don't have to use much.
