I recently ordered the Blue Horizon in 44mm, and have been absolutely thrilled with it. The materials and quality are exactly what you would expect based on the descriptions and pictures. The ring is beautifully crafted, and finely finished with a clean, precise design. There were no burrs, blemishes, or imperfections out of the box. The weight, one of the big selling points of the tungsten carbide used, is immediately evident, and very satisfying.
The fit perfectly matched what I expected based on the sizing ring set, so it's absolutely worth getting those prior to ordering.
I purchased this ring solely for erect use around my shaft only, so no comment on all-day wear or whole package use, but without being indelicate, it performs very well in the moment. The edge of the ring is clearly designed to maximize comfort, which it excels at, and the weight adds a delightful heft to your own equipment. It's received thumbs up from my female partner as well, who says it hits all the right spots.
This ring in particular requires some attention during cleanup due to the recessed groove, but a simple wipe with a towel or small brush does the job wonderfully; there are no hidden recesses or imperfections to hinder cleaning.
Overall, this is a beautifully and exquisitely crafted item, as much a piece of art as it is a tool. It is absolutely worth the price, and it provides a sort of indescribable satisfaction that comes from owning something thoughtfully designed and well made.
