We bought this out of curiosity and figured it was that cheap that it wouldn't matter if it didn't work.
We went in with the right mindset. Technically it does what it says it does.. it covers things. Thats where it stops though, it doesn't blend or set very well and if you can manage to get it close enough to doing that then there's a very high chance that its split.
Theres very little option in terms of shades, this is generally pretty common in makeup but even the offered shades struggle to meet many skin tones.
Purchased this for my mum as she loves the maybelline concealer and has been using that for about 20 years and its getting progressively harder to find, so when we saw this for $4 or so, we figured why not. Shade range was average, when my mum used this she mentioned that it just sat upon the skin, it didn't sink in nor cover any spots/redness which is what she uses concealer for. She has normal skin so not overly dry nor oily. Not the best and won't be purchasing again.
