I tried a sample of them - not bad. I did find them to be very comfortable, but the sides are VERY stretchy so you can't get them as snug as you do with a typical diaper. They also felt a little clinical, being more bariatric in design.
Overall though, I do enjoy the Tena briefs overall for what they are - a cheap, easily accessible, reasonably absorbant, fabric-backed, velcro-tab drugstore diaper. I greatly prefer them to the plastic backed drugstore brands which feel terribly cheap. And I don't feel guilty disposing of a barely used Tena when I know I won't have the opportunity to thoroughly enjoy a more expensive diaper.
