Uovz 512MB Memory Hong Kong CN2 KVM VPS Review

Details: Uovz: 19 yuan/month/512MB memory/10GB space/50GB traffic/KVM/Hong Kong CN2. From the test results, it is much better than his OVZ VPS. The network speed in mainland China is very good, the bandwidth is sufficient, the price is not high, and the stability remains to be seen. Worth holding!
