Not good!

Recently purchased Gelaze gel polish (not sure the name of the color, as the sticker on the bottom fell off, but it's a neon yellow), and I am extremely frustrated with the quality of this polish.
The consistency is too thin and pigment is minimal. I applied first to my toes (without a white gel polish base), the application was poor, each coat went on streaky and uneven, even after 3 coats (not including the base and topcoats).
So then I figured a white base would've given better results. Which is what I used for my fingers. But the results were even worse. I didn't even finish my first hand out of frustration and disappointment and waisted time.
If anyone out there has any tips or advice as to what I may have missed or done wrong, please feel free to comment! Thank u in advance!
