Ten whole days is a long time in nail polish days! Although this product is pretty good it definitely does not last ten days with or without the Revlon base and top coats! I do like the Revlon nail polishes but its really doesn't last that long at all.. It probably would if you were a princess and had nothing to all day :)
The colors are very nice but for me some of the colours do come out a little bit streaky because of the size of the brush.. I am not a fan of the brush.. If it had a better brush it would be much easier to apply and I would give this more stars!
I love how you can find these pretty cheap quite often. Theres a huge range of colours. the formula is good, not amazing or comparable to high end ranges, and can be a little runny (atleast 2 coats).
I personally enjoy changing my nail colours regularly so the longevity isn't a big deal for me. These ill probably leave on for a week.
