At one time I had purchased, used, and/or handled every dryglove ring system designed to integrate with the Si-Tech QCS Oval wrist ring system.
The Ellipse ring system works very similar to how the Waterproof Ultima DGS works. The primary issue I had with the Ellipse rings is that the oval shape means they have to be indexed/aligned when initially setting up and then each time one dons the glove rings. I already had the Ultima DGS rings and found it easier to Don that system when I had all my gear on because it was round and it did not need to be snapped together as "precisely".
Eventually I tested and reviewed the Rolock 90, and found of all the systems I had used and/or handled it was the easiest to set up and use...particularly when fully kitted up on really cold weather days.
It is important for me to state that I was not concerned with the "low profile" of the system. I was purely trying to find a system that was easy to setup and easy to use...those were my priorities. If one's priority is a ring system that specifically has a low profile profile, then the Fourth Element Ellipse rings will meet that criterion.
