Hello

ive got these as a full setup on my router. bought from Zappautomation and i have never had a problem with them except 2 driver bards burning out but that was my fault with the wiring.

Once i put right board to right power supply all has been faultless and that will be around 5 yrs ago.

i recommend them no problem. Expensive and closed loop but you get what you pay for.

Hope this helps.

Cheers
