Here is what the CK3 kit looks like.

A closer look at the probe reveals two LED's. The probe's purpose is for retrieving the key, inquiry and identify.bin files. The LED's indicate whether the probe has power, that would be the blue one at the top, and whether you have a good connection to R707, the green one at the bottom. When you insert the probe into R707, the green light will come on and stay on.

A good look at the CK3 itself. It has a serial port, serial to USB, a molex connector for power and the connection that goes between the DVD drive and the CK3. It also has a power switch for power cycling the drive, an eject button, and a mode button. The mode button is only for hitachi drives and when you are working with a samsung, benq or lite-on and power on the CK3, the power light LED should be blue and not red.

The CK3 all connected up and ready for business. In this picture, I'm working with a lite-on drive and I have it connected by the USB to serial port.

Here is the R707 hole. This is where you are to insert the CK3 probe when the time comes to get your key, inquiry and identify.bin files. The actual place is circled in red.

Now, this experience went very pleasantly. I have to say that before you open up jungleflasher to start this project, you need the drive in a half-closed state. To do this, power on the drive, press the eject button on the CK3 and then power off the drive. Then close the try by hand till it's half close and then power on the drive. Also, I should note that if your using a via card, the possibility of your PC locking up on you after clicking the lite-on erase button is pretty good. You may want to use iprep to flash with if you do have a VIA sata card.
The CK3 kit is of excellent quality and is very useful, in fact if your working with a lite-on drive, you have to have one of these or a Xtractor 360 or a rs232 TTL converter of some kind to complete your project. The CK3 has worked very well with hitachi's, samsungs, benq's and lite-ons.
I would highly recommend this device to anyone wondering if it is worth the price. I give it a 9.5 out of 10. I'm only taking off a half a point because of the price, but, the Xtractor is pricey as well so it all evens out.
Here is a video of the lite-on flashing process.
