These fins are among the best I've used - at the moment I prefer the conventional fin design: but I'm slowly investigating the side of twin channel models. The Plana Avanti Quattro fins are very durable - mine have been through a lot and they still look new, rather than the numerous pairs of fins which look like they've just been discovered in a glacial deposit after a couple of dives! Propulsion is brilliant (thanks to their "4 channel design") and they present far less stress on the legs than other models I've tried. The ABS buckle system is great - it endures easy donning of fins (simply slip the strap over the heel and click both sides) - the lock on the side has meant that I have not once had to chase after a fin that decided it wanted to abandon me: and yet they are the easiest fins to take off after a dive... unclip the buckle, waggle the fins left to right and bob's your uncle... or maybe your aunt in todays world.
With a wide choice in colours to match everyones dive fashion needs... you can't go wrong opting for the Mares Avanti Quattro.
