IMO, they are real K2s, but which K2? Price alone tells me it could be an entry level ski, but maybe it's just a poor seller from a few years ago because there was no demand for a higher level ski in SA, or maybe it's a lost leader. . A Pontiac G3 Wave and a Cadilac CTS V coupe are both "real" GM cars, but they are not quite the same.
Also imho, entry-level skis are a complete waste of money; your skills should outgrow them in a few days.
So how do you tell? Go to a real ski store and fondle the good skis. The main difference between entry level and and upper level is in the torsional rigidity and longitudinal flex. See how hard it is to twist the tips and tails while holding the centre. See how easily or not they bend. Remember that as a very general rule of thumb, easier bending is better in soft snow and harder bending is better on hard snow. Torsional rigidity is a good thing.
Now go to SA and do the same with the skis you are thinking about.
You may just end up buying a good ski from a good store.
