This is pack of three Castle Creations 6.5mm Polarized Bullet Male Connectors. Polarized connectors have a place in the hearts of many modelers as they make it impossible to destroy their expensive electronics and batteries by plugging them in backwards. However, they have been lacking a connector capable of extremely high currents, constantly having to increase their voltage to maintain amperage levels. But what do you do when you’re maxed out on voltage and your setup requires more amperage than battery connectors on the market will handle? What if you don’t want to or can’t increase your voltage due to size constraints or competition rules? The answer is simple, you go green. The Castle Creations polarized connectors will handle up to 200 amps of continuous current (for the 6.5mm version; 75 amps for the 4.0mm connectors) without breaking a sweat at any voltage level used in R/C applications.
These are the highest rated polarized connector on the market. Not only that, but they’re user friendly too! Castle Creations has added ridges to the housing making them easier to grip, they accept up to massive 6 AWG wire, and they're marked "Battery" and "ESC" for easy reference. Batteries and ESCs aren’t the only things they’re useful for though. Use them on your charger leads, parallel and series harnesses, high current amp/watt meters, and anything else that needs super high current. They’re what "going green" should REALLY mean!

These are the best battery connectors I've ever used. I used to run EC5's but they'd come unplugged during hard hit bashings, these babies don't. they are harder to plug and unplug but that's what makes em so beefy and 200a rated.
If you figure out how to properly install these, they are a breeze, easier than EC5s.
As far as the 1 star review guy, I'm guessing he was likely trying to install the bullets from the wrong side of the connector. they go in from the connection/mating side (not the back), opposite of how the EC5 works. the idea behind this is then the bullets can't possibly come popping out of the back like the EC5's can. This also makes them much easier to install than the EC5's because once your wire is soldered all it takes is a tap into the empty barrel end to set it down into the connector, instead of like an EC5 where you have to annoyingly tap it in from the back/wire soldered side.
So the procedure is to slide the green connector onto your battery leads FIRST and then solder the first bullet onto the wire, snap it in, then solder the 2nd and snap it in.
Not sure about the comment about them not lining up either, the ends are tapered and slide right into the barrels effortlessly, I've never had any kind of issue with that. Perhaps he was putting the wrong barrels into the wrong plastic connectors which I know i did accidentally once with EC5s.
