OCIA.net checks out the Vantec EZ-Grip Molex Connectors in their latest review. Below is a direct quote from the review:

"I inserted the molex removal tool provided in the kit. Let me just say that this tool easily cuts the time of the job in half. When I put the cable sleeving kit on originally, I found that removing molex connectors without an appropriate tool is very time consuming and hard on the hands. However, using the tool that is provided, all that is required is inserting the tool, and pushing the knob on top, similar to the working of a syringe."
