I had previously used a counterbalanced Scotty X7M and just didn't get on with it, the problem with the Scotty was the weight was fixed with epoxy in the top of the shaft under the grip so changing was a real pain as you can imagine. It lasted a year on and off before I got rid permanently.
On the brighter side I purchased and installed a new Superstroke Mid Slim 2.0 counterbalanced pistol grip to my Ping Vault Voss last Friday and the change was outstanding.
Grip has a screw top and came with both a blanking cap (I.e. no extra weight) and a 50g counter weight. Tested with both the cap and weight screwed in and noticed my stroke was much more consistent with the weight in so would say there is a definite improvement (at least for me).
What i also like about the Superstroke is the ability to easily change the weight through the butt of the grip itself, being with a hex tool and a couple of twirls you can easily switch weights (without the hassle of having to pull the grip and get the burner on to remove the epoxy/weight).
Superstroke aren't the only company that sell counterbalanced grips, i do like the ability to change the weights easily without messing. Before purchasing the Superstroke I had looked at the tour lock system but postal/import charges to bring to the UK just made it too expensive an option to justify (postal only was same price as my new grip).
