Ceros

Top quality and I like that extra "horn" piece at the top to help prevent things from moving onto the spine side.

Works great with the Edelrid Mega Jul, Petzl grigri 2, grigri plus, BD ATC guide, Wild Country Revo and even a Munter Hitch. Works okay with Mamoot Smart Alpine, but is slightly narrow and requires attention from the belayer. Screwgate closes nicely and quickly, unlike Metolius. Rope end is wide enough and with round profile so that a munter hitch works well, even with 10mm stiff rope. Works well on rappell. Anti-cross load feature out performs the similar features on both Black Diamond and Edelrid belay carabiners. Probably the best belay Carabiner I have tried and I've tried it huge number. The Grivel Clepsydra is the only other that compares, but most people don't like the twin gate on the Grivel.

This biner is really well made and operates smoothly. Most importantly it completely eliminates the possibility of cross loading a grigri. I have tested it in every possible orientations and it always ends up loaded on the major axis. The captive bar works well, it is tight and the belay loop won't come out. Also opening toward the palm makes it easier to operate with one hand. The material and finish is top notch. I will be adding more DMMs to my rack from now on.

Really like this carabiner. Works perfect my Grigri. The carabiner doesn’t rotate, the Grigri stays in place. Make belaying super easy. Well made.

While this works great with a grigri it also works great to safely secure hillsounds or microspikes to my pack.

I love this biner. It works just as expected, and the quality is great. I also have the Black Diamond Gridlock. If I had to pick between the two, at this time I would pick the DMM as I like the Rhino notch which keeps things in order.

Prevents cross loading of a Gri-Gri which is nice but I would not use it on any multi-pitch outdoor stuff due to its weight and how it doesn't hang on a gear loop as nicely as a typical carabiner. The extra step to remove it increases the likelihood you would drop it.

Bought this to prevent my GriGri from crossloading my normal caribiners. Does the job. Build quality is fantastic, screw lock and gate both feel solid.

In Kombination mit dem Gri Gri Weltklasse! Der kleine Bügel muss nicht nach oben wie bei anderen gedrückt werden. Deshalb kann man den Ceroa auch mit einer Hand einfach bedienen.

通常のMHSだとグリグリがズレて、マイナーアクシスに荷重が掛かることがありますが、このカラビナですとグリグリがズレることがありません。グリグリ専用として売られているモノではないですが相性はいいと思います。

Great quality caribena, well made, sturdy & does what it's supposed to! 25KN ↔️ / 7KN ↕️ / 7KN open.

Direi buon prodotto, fa il suo e sembra farlo bene

When using a normal carabiner I would always have issues with the rope catching on the gate when pulling rope through and rotating the carabiner sideways. This is quite dangerous since carabiners are meant to distribute forces through the top and bottom, not the sides. Switching to this carabiner solved that problem since it captures your harness at the bottom and forces the carabiner to stay upright. It also has a solid construction and a satisfying sound.
