The flex gun is by far one of the most intimidating tools I have ever seen.

Look at their warrenty and read it carefully. "We will not accept returns if the item was damaged by improper installation, customer abuse, and normal wear. We will only accept a return if it is defective."

Wow so basically if a defect shows itself under normal conditions they can deny you the warrenty.

CVJ in my opinion is the best option for axles.
