Help with legitimacy of a Njoy Pure Wand!

Hey everybody, a fetish shop near me has an Pure Wand-Style toy on offer for 80€, apparently an Original Njoy, but nothing on the website states it's Njoy, except it's called a "Pure Wand" however no mention of a brand, which makes me skeptical. I'm very tempted to buy it, however, from reading lots of reviews here something that sets the original Njoy apart from knock-offs is the weight and with that, the pressure it puts on the p-spot. The shop's website states a weight of 520 grams (so 1.1 pounds) is this accurate to the original? I haven't found a source for the original Njoy weight online sadly, so I'm asking the community! Thanks in advance!
