Looks very similar to one of the AB airbrush range. I use one of their's, with a detachable side cup, and it's been excellent. Even if it only lasts a year or so, at that price, it's well worth it - I thought mine was cheap, at the equivalent of around $45 !!
Follow the advice given, especially the cleaning, and you should be OK.
But - practice, practice, practice and lots more practice before using it 'live'. Spray onto paper at first, just using water, to get used to the trigger pressure and action, then progress to water colour paints, practicing various fine lines, broad patterns, 'squiggles' and so on, and practice signing your name in your normal signature, as you would using a pen.
Once you're happy with that, try using the paints you'd use on a model, thinning at various ratios, and then move on to spraying on a 'scrap' model. Different types of surface materials will give varying results, and you need to be aware of this, and how the 'brush, and the paints, perform in these circumstances.
