Pro mini programmer

I just found this Arduino programmer. Has anyone used this? Will this program my pro mini?

That is not a Arduino 'programmer' as it is not a ICSP programmer but rather it's a FTDI based USB serial converter. As such it will work to upload sketches to the pro mini via standard IDE uploading. But if you wish to be able to burn bootloaders to your pro mini then you need a real 'programmer', which can be another arduino board running the arduinoISP sketch.
