To me the quality of Savox connector pins look like they're of superior quality by design compared to generic ones.

Plus I like the fact that on the connector there are angled edges on one side and as you can see there is a ''S + -'' debossed on the case which helps alot with blacked out wires or with a 12 year old working on his car...just trying to make things as easy and convenient as possible for my son since there are so many things to think about at once and for myself to prevent reverse connections, just in case I don't have 100% focus for whatever reason.
