Light and Small
I used to carry my DB Ascenders with me while canyoneering because they are easier and quicker to climb a rope with, but I didn't need to use them very often and they are heavy. I bought these tibs to replace my DB ascenders when canyoneering and they have been great! they are super light and small and they do the job well if you know how to use them (read the instructions and practice at home first). I have used them to climb a 9mm static rope once and used them multiple times to help grip the 6mm pull cord to pull a rope down from a rappel. I use the BD Rocklock carabiners and they work will with these tibs. My only complaint is I think the price is higher than it should be for these little aluminum ascenders, but they are worth it if your canyoneering and want to save some weight. be sure to by 2 because they are only sold as 1.
