Dogtra 2300 NCP works exactly as advertised! I used it as a basic training tool to put out a low continuous stimulation when training come, down, sit etc. very successfully. And as a correction stimulus at higher settings to solve unwanted barking and behavior problems. it is sturdy and easy to use. Best training tool I've used in my 60+ years of dog training. And, an additional plus: If you need to talk to a tech about a question or problem, there is no waiting. the the support is friendly, professional and knowledgeable. Really pleased with this product.

I've had a Dogtra collar for years and it's the best. I bought this two dog unit when we got a second GSP. It works great and has the familiar feel of my old one (all the buttons are in same places). It also has a longer range and a digital display, which are nice upgrades. Only downside is that the receivers on the collars are a little bigger than the old one. This hasn't been a problem and the dogs don't seem to notice the difference.
