Familiarity: I've put it through the wringer
I have a small Rkt 9 frame which does not have enough clearance to use a regular bottle holder. I tried a cageless bottle which did not work out well, just too hard to pull the bottle off and put back without stopping. The side loader was a little weird at first cuz you have to push the bottle in, but after a few tries it is as easy as a regular holder. Also has a tight grip, so no issues of losing bottles. I got the left sided loader so I can keep my hand on the rear brake while drinking. Highly recommended if a regular bottle holder is not an option.
