Both ends seem to be equal diameter so they work fine for me? I bought 2 boxes of these a few months ago.
I just add a tiny dot of Black Horse Repair solder paste on the wire before heating to get the solder to flow better over the 2 wire ends because the solder doesn't always flow through and stick to all copper wires, but with a tiny dab of that solder paste it forms a strong connection every time.

What are you talking about? They are the same. Have used these types for years. They're great for a quick fix. Add a dot of flux and solder to make an even better connection. Gentle heat gun and they'll be solid. Will get another set, it's a good deal, last I bought was also 120 pieces for $10.99 in April 2020.

Is the ring in the middle supposed to help heat solder or is it containing/made of solder itself? Pic is unclear and I've never used these.

I have a set just like this. Works great on trailer connections with a heat gun.

one side on the red is smaller than the other end, if you read the other reviews you will see the same problem
