I travel - A LOT. That means that my dogs travel - A LOT. So, in addition to traveling and just going outside and for walks while home, they need a variety of leashes. I also have 3 different sized dogs so I have to make sure that all sizes are covered by what I have. With one of them being a potential service dog, this leash is especially nice because the control handle is attached to the main lead. This is extremely helpful for keeping the dog close and not having it flop around all the time when you are not using it. You do have the option of releasing it from the main leash but I'm really not sure why you would want to do that.
The bowl is also great. It collapses easily but not so easily that the dog accidently does it while using the bowl. All three of my guys are able to use it without any problem. This is perfect because I only have to take one bowl that is accessibly while driving/at rest stops to give them water.
