Excellent material, with certifications, manual, excellent quality. I will buy more as soon as possible and recommend both the product and the seller.

Very well constructed, I have already bought three in natural aluminum color and this orange one, and I will buy more. It has CE and UIAA certifications and is identical to those sold in Brazil, which are imported and receive the brand engraving and NBR certification.

The carabiner is well-made and seems to be of good quality. It locks very efficiently. But I don't know if I would have the courage to risk my life using this carabiner.

The item is of excellent quality—very sturdy and attractive. due to an oversight on my part, i didn't pay attention to the measurements in the listing. when i received it, i realized it was too big for my needs and had to return it... my sincere apologies for the oversight—it was my mistake! however, both the product and the seller are excellent. many thanks!

Dale Sanford

Used for horizontal rigging.
Since you can unlock it by simply rotating the lock ring, it is highly dangerous and inappropriate for rock climbing.
The feel and smoothness of each part are good.

They seem good. They are lightweight and sturdy. The lock slides easily and the handling is quite similar to other brands I'm used to. I'll test them with a load and come back to give my opinion.

It's really good.
The operation of the gate and lock is also super smooth.
I would like it if there was a triple lock.
