Does what it should. No complaints. Only minor detail is that it's marked as a positive terminal. It's got a sleeve to work on either post, so it works for +/-.

Very good offer.
I use them all the time when working with an electrician.

Using these with a quality crimping tool can stop frustrating wire pulling out problems. I switched over from allen key clamp type connectors to ring terminals wherever possible. Sonic has the best price on these by far, you cannot go wrong.

Cheapest 4awg ring terminals i could find and they work just fine. I used the flat xscorpion 4awg wire... Fits fine.

They do what they do... Worth it to keep your system lookin pro!

I chose to buy these because of the price and quantity compared to the Rockford Fosgate crimps I was looking at. I was a little leery at first since they were so cheap but they worked really well with the crimping tool I also purchased from Sonic. I wanted to solder my connections but don't have a soldering gun so I chose to crimp and has worked great so far,nice tight crimp and passed the pull test every time. I used them installing my mothers Rockford P1000.1 bd and 2 RF T1D412's and will be using them to install my 2nd battery,RF 10 farad capacitor, RF T2500.1bdcp,P500.2,P500.4 and a P400.4 in my own truck. I would highly recommend these crimps.
