only Razer problem with profile switching

I wanted to switch to razer ecosystem with mice, keyboard and headset, some longer time ago. Meanwhile I'm far away from this, only use the orbweaver with Synapse2, sold or disconnected naga and keyboard. Actually I'm running Logitech, Steelseries, Roccat and Razer drivers in parallel. The only driver, that is permanently making problems is the Razer's one ! All others work fine, let me programm keys, macros, switching profiles according to game executable without delay. I can use them online, offline, no crashes, no CPU workload. Only Synapse permanently has problems, loosing profile, switching back and foward withount sense. Once more: Why is only Razer totally incapable of producing smooth running drivers for their expensive equipment ???
