Sleek polishes didnt quite "nail" it for me...

Sleeks NAILED polishes caught my eye in superdrugs as they are 10.5g in size, only £3 and come in a huge range of colours.
So without even trying one first i snapped up "pastel pink" - the one i have pictured, "florida" - a bright orange, "bare" - a nude and "truffle" - a bronzey gold. Unfortunately i wasnt very impressed at all !!! just another sad case of cheap nail varnish looking just that, cheap! Thick and 'glooopey' is the best way to describe them. They take forever to dry and when they do they are streaky and extremley patchy.
Sleek website describes them as "quick drying.. long lasting.. instant full coverage with one stroke and silky smooth". I found them to be none of the above.
Is this just me? Has anyone else experienced this with the sleek nailed range?
I used a base coat, did not get to the top coat stage as i removed the polish asap when it dried!!
