Does anyone have experience with an all-in-one martingale style collar? It's like the all-in-one kennel lead/collar, but instead of a plain slip collar, it has a martingale collar. Here's a sample (not to endorse a particular seller; I was just poking around online.)

Just to explain what we are looking for: on a normal walk, our dog wears a buckle collar and leash with all his tags.
We do not leave a collar on around the house, for a lot of reasons. Whenever we take our dog out, we put on his collar and leash.
We don't have a fenced yard, so when we go out to potty we just clip on his collar. The combo leash/collar would replace his regular collar for potty breaks and car trips, not for regular walks. Kerry's story in another thread of a dog breaking his collar and getting loose on the highway scared me, as Jack is mentally incapacitated when it comes to cars and would cheerfully step right in front of one without a moment's hesitation. What I am looking for is something secure enough he would not slip/back out of it, and easy to put on and off. Before I spend money on stuff that does not work, I thought I'd ask around. PetSmart does not sell all-in-one combos, but the nice lady there recommended the martingale style over the regular slip style, as it releases more easily when the dog is relaxed.
Jack isn't a terrible puller and is more inclined to balk behind me than pull so hard in front that I need a choke collar (though he will pull a bit).
Thanks in advance for your feedback! If you haven't used one but have experiences with something similar, I'd also appreciate hearing.
