These are pretty good quality connectors, everything fits together nice and tight. However, the product picture shows that the female connector is polarised (one circular bit of plastic with 1 pin, and one elongated bit of plastic with 2 pins), so that it can only mate with the male connector in 1 orientation. However, the connectors I got had a slightly different shape on the female connectors, with 3 circular areas with 1 pin each (shown in the photo I uploaded), which means that the connector can be flipped around and still plug in - on a brushless motor, this would reverse the motor direction, which could ruin your multicopter. Overall I like the connectors, but you need to be careful using these ones, and the product picture should probably be updated, or the correct stock part swapped in (I'd really like the polarised ones instead)

Very nice, sit firm, easy to solder. Compatible with normal 2 mm gold plated plugs. Very fast shipment.

These things are TINY! I didn't expect them to be this small, they will be great for making strong servo connections to things! Picture attached shows size compared to standard servo connector.

Really wanted to love these connectors. Perfect size and build quality is very high. Problems is they are not polarized. Can be connected either way. Also, they are very difficult to disconnect once they are plugged together. Will need to use pliers to pull them apart. What good is a connector that you can't disconnect?...

That connectors are best choice for me , since i use them to connect esc with motors , very small and light + durable and plastic greay cap fits very tight so it will not fall off.
