I've seen somewhere on Instagram someone bought one of these Garbaruk knockoffs, when he stood on the pedal the crank started flexing, and when he stomped harder it broke. Garbaruk responded with similar video with their original crankset under load, no flexing noticeable. Just avoid fake products, they're almost never good. I bought a Zrace RX crankset for half of that price (without chainring), and it's pretty decent.
