Best experiences with wrist links

So the sun is shining and finally here in southern Ontario the temp is creeping up to mean outdoor time is back to being a regular daily thing. I have a quad stroller and want to get walking again. I have a 5th kid this spring though...The walker is without question a particular child as he is so heavy. It's hard for me to lift him...I'd guess he is about 50lbs.....solid as a rock and there is no way I can push him in the stroller and have the older kid walk. So, I'm not thinking any kind of kiddy step/trailer/boogy board would help, but he is prone to resistance, so I don't want him to have any opportunity to run off so I want a wrist link so even if he stops walking in a moment of stubbornness, it will bring me to a grinding halt also.

Has anyone had positive experiences with wrist links that they could make a recommendation? I could buy any old thing but wanted to know if anyone had one they tried and liked.

Thanks in advance.

When I have a walker(s) that I don't think will walk nice or I'm afraid they're a runner, I use the backpack harnesses. It buckles around their stomach and I attach the other end to the stroller or to my wrist. It has 2 buckles so if they were to undo it, I'd notice before they got the 2nd one undone. They have always worked wonders for me.

The only thing that I don't like about them is that it does create a lot of "fake" independence and I sometimes wonder if it will create a habit of the child not wanting to hold hands with an adult when needed. To try and stop this, I make the child hold onto to the stroller as much as possible (some sidewalks don't always allow room for this) and especially when we cross streets. To shorten the "leash", I just wrap it around a few times on the stroller handle or my wrist.

They sell them at Walmart for $10 and come in cute little animal options.
