此RX Unit #12是一款接收器單元，設計用於Dogtra 1900S系列，包括1900S和1902S型號。它作為替換或備用零件，讓您的訓練系統維持正常運作。
My old receiver finally gave out after years of use, and this replacement unit synced perfectly with my 1902S collar right away. The build feels just as solid as the original, so I’m confident it’ll hold up the same way.
Paired it with my 1902S in under a minute and it’s been rock solid through a full week of training sessions. The receiver feels just as sturdy as the original that came with the system, which is exactly what I needed for a backup.
It arrived quicker than I expected and the box was intact, which I always worry about with parts like this. The unit itself fits perfectly into my setup, and the connection feels solid with zero wobble where it mounts. Really glad I grabbed this instead of struggling with an older piece.
