We use them too and I have never had any issues- although we have the kind with the 2 piece lid (are they all like that now?) and I somehow manage to lose the lids pretty often. Not the rings, the flat part. Haha- I sound like a dingbat, I don't know the proper name for those lids.
I have some old ones with the metal clamp and rubber gasket... I like those too but I had to replace gaskets, they started falling apart. I find those to be more of a pain.
They are called "regular lids" ,"dome lids", or "flats".
Rings are also called collars.
Old rubber gaskets can be found at some hardware or farm stores.
They still carry them, because yes, there are people who, still use the wire bail jars to can with.
The 2 gallons ones, I had like 9 last year, I found when out garage saling. Silly me, sold them, when I sold some extra canning jars. Only thing in my defense, I got good money for them

I pick up all the canning jars I can find, pick out the ones I want, then when I get a nice bunch of extras, I resell them. Pays for what I keep back

I also have a nice collection started of antique ones. I like looking at them. If worse comes to worse, I can always use them for dry storage.
