Price wise Revitalash does totally sting for a student - but if you're an avid makeup lover like myself then it's worth the investment! The product lasts a long time and you'll reap the benefits in no time. I'd suggest to take a photo before you start using it and after 2 or 3 weeks of constant use to see the real effects! Try to apply as evenly as possible otherwise you can end up with some lashes longer than others.
Packaging wise, sometimes I do find it more difficult to open - mostly because of the smooth finish on the tube. The brush for application is a super fine brush - similar to a liquid eyeliner - and very easy to apply!
