haisstronica 260PCS Marine Grade Heat Shrink Ring Connectors-Heat Shrink Wire Connectors Tinned Red Copper #10,1/4",5/16",3/8"(3Colors/4Sizes),16-14 22-16 12-10 Gauge Insulated Ring Crimp Terminals

I got tired of trying to find a decent quality 'everyday use' ring connector - there's hundreds of seemingly no-name brands out there, and all of them seem to have high ratings... Not super helpful when the quality varies so widely between sets, so I went ahead and purchased 4 different sets of what I'd figured were 'non-name-brand' ring terminals and tried them out.Turns out, 3 of them were all the exact same connector (down to the hundredth of a millimiter) - only this one was different, and significantly better than others.First pic shows the thickness of the 10-12awg connector from Haisstronica, with the second showing 'the others' - it's close to ~30% thicker, and ~3-4% wider (outer of the ring) with the same size terminal hole. These are *much* better for actually getting the amperage the awg you're using is rated for. Additionally, all the terminals are *actually sorted properly* - all three of the other sets I received were sorted by awg alone, with the ring sizes all being mixed up - makes for much more efficient usage when you've a ton of crimps to make.The heat shrink material isn't exactly 3M quality, but you're not paying 3M prices either, and it more than does the job it was made for - these are the absolute best bang-for-buck option out there imo, very satisfied, and definitely will be buying more of their connectors as I need them in the future.
