I really don't like this product, at first the roll on seemed like an okay idea but its very harsh so basically pointless because I always had to just use my finger. Also after about a week of using it whenever i put it on it would sting like crazy!
Will not repurchase

The rollerball doesn't roll ! The product is hard to get to come out when the ball doesn't roll!!! I tried to squeeze it and some comes out the sides. Ugh. The product doesn't irritate my eyes but doesn't do much either. it's just okay. will not repurchase or recommend. But will continue to use since I can't return it and it doesn't cause any harm just sucks :/ I like Simple's facewash gel though. fyi

Horrible product...it is literally pointless to buy, makes no difference for your under eyes.

This roll-on is super harsh for under the eyes!
It takes ages for product to come out, so if you'd have to actually use the roll-on, you'd be pulling at your undereye area with the bloody thing.
The formula itself is alright - I've left this at my boyfriend's place to use when I stay at his, and I've been getting the product out using my ring finger and patting it on gently with my it.
I've used their regular non-roll-on eye cream before and that formula was gentler and less sticky (as this can feel sometimes), so if you do want to try a Simple eye product, get that one instead - better product without the crap roll-on that will pull at your eyes!
(For the record, I use the Garnier tinted roll-on sometimes and the roll-on on that one works fine.)

Sadly, it didn't do anything for my eyes. It kind of made me look more tired then before. I gave it to my mum if she noticed a difference but I'm thinking to just invest another one better for her because her skin is more mature and I doubt it'll work anyway if I passed it around.

The price is average but the packaging is odd. I personally don't like eye roll ons because it feels too rough under the eyes and it's the most sensitive part as well so it's not worth to buy something that automatically does it for you. Fingers are better tools.

its kinda useless, it doesnt do anything, it apparanlty "softens and smoothes" it made no difference whatsoever, waste of my money, i wont buy it again, but im gonna use it until it runs out now that ive bought it :(
