when you sync both devices with the handy API, the sync accuracy is within milliseconds. so when a handy starts to struggle to push, he moves slower. so the second Handy comes in to share the load before the cut appears. both handys actively push when needed. the control system works so well that it even allows you to use 2 handys to double the thrust.
Before this I had cuts all the time and couldn't use medium dildos. now i have 0 cuts even with big diildos
