I could not help but notice the different styles the tops the of electrolytic capacitors are scored to accommodate can swelling.
1) Simple + (4 quadrants of equal area)
This was the original style.
2) Simple triangle (3 equal areas)
After the capacitor plague became common knowledge, by way of things like computer shops going broke, this new style appeared.
I assume this was done so companies could sort the crappy caps that leak or just fail, from the older ones that do all that and occasionally go into orbit (we have liftoff).
The other styles came later.
CapXon should have just punched a hole in the top.
Sums it up to me.
GSC was equally bad, sometimes the challenge was to find one that didn't have a hole in the top.
Also I remember this scene from the simpsons.
Homer: "Look at these low, low prices on famous brand-name electronics!"
Bart: "Don't be a sap dad. These are just crappy knockoffs."
Homer: "I know a genuine 'Panaphonics' when I see one. And look! There's 'Magnet Box' and 'Sorny!'"
So true for some of these cheap capacitor brands.
