We had some similar handles from Ikea that we decided to replace because they were difficult to use on heavy drawers - you had to pinch them fairly hard to pull open the drawer. I found these on this site and decided to try them. They look very nice, are MUCH easier to use since they have the lip underneath that your finger tips can grab, save space because they don't stick out 2 inches from the door surface like normal kitchen handles, and we like the style because what you mostly see are your cabinet doors instead of a lot of hardware. Highly recommend.
These pulls are easy to install and use. We completely updated our master bathroom with all polished chrome fixtures and this addition of pulls looks so modern. I also have arthritis and my fingers get stuck sometimes with knobs and other pulls. We have a 60in. vanity with 18in. drawers and the large size is perfect(6in.) On the doors we placed them 1.5in. from edge of opening. I was concerned about the thickness fitting over the top, but the vanity doors and drawers work fine.
