Vcm2 of high quality – it’s the BEST
The hottest VCM2 clone model: SP177C&SP177C1, seems the same as this
Vcm2 of good quality
Vcm2 of middle quality
Vcm2 of very bad quality
In summary, good vcm2 clones usually cost $150 around. Never believe in the cheapest but best-quality! You will get what you pay for.
