RDK sensors (original or accessories)

Hello together, I would like to equip my winter bikes (original rims 17) with RDK sensors. In the FAQ I also found the matching part number VW 4F0 907 275 H for my GP3. Is only this (Beru) original sensors to trust or are there also accessories sensors that a tyre dealer possibly recommends to me and which can then be easily learned? Gruss Gerhard
