gREAT PRODUCT - CHOICE OF ELECTRIC OR SOLAR. gREAT $. Instructions were included for training the dog & setting up the "trip-wire" - all worked out great. Now have a very happy dog with no chains & me with no risk of him excaping out an open gate. He has freedom but can still only go where I want him to go without tripping the collar - there is no pain to the dog, it's all in the training! You can have multiple pets on this also, even cats!
