Drive Medical RTL10266BK-T Nitro Foldable Rollator Walker is by far the best rollator I’ve ever used, and I’ve had many others. Everything that used to drive me crazy about my previous rollators has been fixed with this one. The big wheels are great for getting over small obstacles, it has great manoeuvrability and it’s awesome that someone finally ran the brake lines through the metal so they don’t get caught on everything you pass closely. Great design all around.
