It's built like a tank! It's very sturdy. I took it out over some slightly rough terrain, and it did just fine. I didn't realize how much more I would enjoy walking around when I had a walker to rely on and I was able to sit down when I wanted. It's just a joy to get out and walk now. I very much look forward, multiple times a day to go for a walk. Comparing walking In a store with a walker instead of a buggy, the walker is lighter, turns faster, takes up less space. and of course, it helps me stand upright. What I wasn't expecting is it's size. It fits in my trunk if I totally remove the arm height adjustment bars. The back seat of my car (Chevy Malibu) is long enough for it w/o collapsing the height adjustment bars. You can easily collapse the arm height and turn the handles in toward the middle to take up less room if you needed. I do wish the arm height was adjustable with a pin/ball mechanism instead of the screw/nut. It is heavy (est. 30#) so if you have any upper body strength issues, you need to contemplate purchasing this. I am glad the part where a person's forearm rests are plastic like you might see on the arm of a chair vs. a rubber pad. I was thinking that a rubber pad would need replacing, get dirty, etc. The plastic is great and another wonderful consideration by the mfg. It came with all of its parts and great directions. We had it together in just a few minutes. The basket is plenty big for my 6# dog. The picture showed it in purple. I asked, they had it in green. Beautifully made, a lot of thought went into it, and it shows. Thank you Elenker!
