I think this harness is perfect. Everything about it is well thought out, and very well made. The number of handles and their placement, the 4 point shoulder strap, the rear hip support which you can use or not use, as needed. Quality materials, from the stitching, to the outer fabric, the mounting points, the padded underside of the panels, the solid clips, the reflective bits, the Velcro name tags...you can't go wrong.
As a senior dog owner, (12.5yr 90lb lab/gsd), he's still active, but his back legs have his getting up a littler slower over time. He collapsed recently on a walk, when he pulled on his leash and that shifted all that force to his hind legs. He strained something and was unable to weight bare for a day. Had to leave him there and jog back to get my car and lift him into the back seat. It was scary. We though he may never be able to mobilize again. Thankfully, he's a strong boy, but I wanted to get a harness like this immediately. With the rear leg/hip support, I can vigilantly walk him, and if there is something that is going to make him pinged, I can hold that rear end up by the handle (of which there are 4, very well placed), and keep him from injuring himself again. And it's also perfect for being able to quickly lift him into my car, which its height had become to difficult/stressful to take him places. He's still fine with stairs, and otherwise very healthy. But if there is a time where he may have difficulty with stairs, but is still mobile and happy on his own, I know I can use this harness with the "luggage" strap, 4 point and handles to carry him up. (Also useful for dogs to trim their nails and keep them in "air jail" lol.
Anyway. Worth every penny. It's not going to tear or break on you. It's the best design out there in my opinion, and I spent some considerable time looking at many options. I want the best for my sweet 'old boy, he deserves it, and I feel confident that I have provided that with this harness.
