I have never purchased any of those premade kits. Always found them to be too expensive for what they were. Still a quick and easy way to have something especially if giving as a gift and having it shipped. The bags look good. I would look up several and see what seems like the better deal or use them to get ideas as to what to put in it.
Since you need some of that first aid items around the house - buy stuff at the big box store or medical supply store f you got one nearby. Pack up something for each vehicle and stock the rest at home , camper, boat.
I have always just got the items I wanted/ needed and packed it up . Found I could do it cheaper. With hand tools look at pawn shops.
On the First Aid kit let me make a case for adding a Shot Kit- a Package of Quick Clot, large dressing and a tourniquet. Perhaps even a needle to decompress a sucking chest wound. Hunting accidents and hell now days a trip to the mall.
Example of one type of prepackaged Shot Kit

Education - a Stop the Bleed class, Red Cross First Aid , Wilderness first aid and a CPR course always a good idea.
Waiting to be a Bronco owner got a base model on order. So someday, maybe?
