LetBox 1GB memory 230GB space Los Angeles KVM VPS review

Details: LetBox: $3.5/month/1GB memory/230GB space/2TB traffic/KVM/Los Angeles This IO is so awesome! The network is Los Angeles Psychz, which is great! According to reports from group friends, this company often loses data and secretly replaces hens. However, the model I reviewed was purchased half a year ago and no problems in this regard have been found so far.
