I bought 2 of these to keep my new Entlebucher puppy from driving my older, grumpy Border Collie crazy, and to keep her safe.  He doesn't get her puppy play and gets very defensive. The gates work beautifully.  They are easily installed without tools and are easily opened and closed.  The safety latch can be used as needed, like when I don't want my 3 y o granddaughter to open them.  I would order these again and would recommend them for use with both pets and kids.  I can't wait for the puppy to grow large enough that she can't fit through the cat door so I can leave it open for my 2 cats.  All bases are covered.  Thanks, Wayfair for the rapid shipping and the good price!
