The Cardas clamshell is very fragile and not well manufactured. It's almost like "you touch it and it breaks".
The Furutech FI-15 clamshell is actually very durable. I have actually switched one of these FI-15 between about 5 or 6 different cables before one of the edges actually broke. A good way to handle it is to have the bottom clamshell completely down while you tighten the clamp screws on the top with the top clamshell open. The bottom clamshell actually helps hold the unit while you tighten the screws (and then vice versa with the top clamshell).
I don't like the Wattgate clamps as much. Once you use the Furutech clamps, you will find that it's actually a very good design. It operates in a similar way to the Wattgate clamps, but it is definitely superior. You unscrew the clamp and it opens up a space in the hole. The Furutech clamp actually forces the wire into a curve so that you have more contact surface to the plug conductors.
The IeGo connectors are definitely low cost, but just remember, you get what you pay for.
