What is the best choice for you?

The PetSafe is less expensive, but you need to buy batteries from time to time, the RFA-67D battery lasts about 3 months.

Battery life may vary depending on usage and whether the dog is often in the warning or correction zone.

You can also put the battery in off mode to increase its autonomy.

If your yard is not that big and your dog weighs more than 8 lbs+, you can opt for the PIF-300.

It remains to be seen whether you prefer a rechargeable or battery collar, the Stay and Play charge lasts approximately 1 month.

Note that the internet battery of the Stay and Play wireless anti-escape collar cannot be changed, so you must buy a new receiver in the event that the battery no longer holds a charge.

The receiver and battery are guaranteed for 3 years, so no worries during this period, thereafter you can buy the receiver alone , no need to buy a complete kit.

Transmitter:

The PIF-300 transmitter is almost twice as large, the stay and play transmitter is very compact and takes up very little space and, first of all, it is more powerful and covers a larger radius.

In conclusion:

Both systems are very good, our choice between the two is the Stay and Play, because it is suitable even for small breeds, it covers more and the transmitter is smaller, but it is up to you to make your choice.
