The Mini Educator RX-090 Receiver can be purchased to replace a lost or damaged receiver or to expand a 1-dog system to a 2-dog system. The receiver comes with 5/8" contact points only and does not come with a charger.
The receiver is sold as a "bare" receiver meaning that it does not come with a collar strap and you will need to select one from our collar straps page. If you are expanding a 1-dog system you may want to consider purchasing the splitter cable so that you can charge all 3 components at the same time.
Please note that the RX-090 Receiver is not compatible with the older TS ET-300 model that was discontinued back in mid-2015
