Comparison of different primers

Hello, hope everyone had a good holidays! I've been so busy with X'mas and as my son's turning 3 soon, have been busy preparing for his 3rd birthday party.

Anyways since I'm having free time now, thought I should quickly make a review on the different primers which I have.

1. MAC Paintpot- Bare Study
2. HighVoltage eyeshadow base (http://www.highvoltagecosmetics.com/) - USD$5.50
3. Forever Glamorous (http://www.foreverglam-makeup.com/)
4. EG Minerals perfect eye & lip primer cream (http://www.earthenglowminerals.com/) - USD$9
5. Detrivore primer (http://www.detrivorecosmetics.com/) - USD$6
6. Earth-glo Minerals "Stay put Eyeshadow primer potion" (http://www.earthglominerals.com/ or via Ebay store) - USD$4.50

I do have Urban Decay primer potion as well but it's new in box and I didn't wanna open it as yet cos I have the above which are yet to be used up! But I'm sure alot of you would have heard good stuff about the UD primer and yes, UD primer is good but if you're comparing of the prices, above are the alternatives which you may consider of!

Here are the following pics to show the results of individual primer:-

Starting from left is (1) MAC-Barestudy ... to extreme right is (6) Earth-Glo minerals

Can you see the differences? Eyeshadows are more vibrant on Foreverglam primer, Detrivore primer and Earth-glo minerals (which I've just recently bought and received today)

Hmm... my personal opinion... the least impressed ones are (1) Bare study and (4) EG minerals.

The most vibrant one seems to be (5) Detrivore primer.

So there you go... hope my info does help you in finding a good primer without having to spend too much! :)
