Some of these eights are made in Europe, and some in Asia. Some are rebranded eights made by one manufacturer for others.

Each of these eights is 170±1 mm. tall and 170±2 mm. wide. Their weights fall in the 269±20 g. range. Although similar, these eights are not identical, and close inspection will reveal some minor differences in their shapes. Thickness variations account for much of the wide weight range. None of these affect their performance to any noticeable degree.

The Climbing Technology Ltd. eight is similar, but the ears are shaped differently. The Climb Right, Version B has a similar design, but it is a milled eight and is significantly smaller. There are several Kong steel eights that also have similar designs, some about the same size as the Kong Big "8" (805.06) in the table, some smaller.

The eyes and ears on these eights are larger than they need to be for most uses. The belay slot is a reasonable size for a Sticht slot, and insetting part of the slot into the useless portion of the upper rope hole reduces the length of the eight.

Like all rescue eights, these are too large and too heavy for an individual-use eight, and I see no reason to choose them in normal caving or climbing applications. I don't interfere with natural selection, not wanting to deal with the politics, but I question whether these are really the best option for rescue applications. They can be used, but there are smaller and lighter devices that will work better for anything I'm likely to do. The bigger-is-better crowd seems to like them, but I don't rappel on battleship mooring hawsers and I have no need for these.
