Yes, I like it so far
Mostly good, as expected. It's nice and solid. I'm upgrading, or sidegrading (that is, moving laterally), from a Helavo H1150, partly because the Helavo's seat isn't comfortable enough for me (the Nitro's sling seems to work better in my case) and partly because I had a previous Helavo bariatric (H1050) model's frame tube stress-fracture above one of the wheels and collapse while I was leaning on the thing turning a corner going down a wheelchair ramp. I had some luggage piled on the seat at the time, which of course is a no-no, but even so, I'm sure that the combined weight of that plus my leaning on the handles was less than the supposed 500-pound capacity. So even though I replaced the broken one with another Helavo simply as the quickest fix available in the circumstances, I also started shopping around for a different brand. If the Nitro Sprint HD were available from Amazon, I would have bought one then instead of the H1150. Making the Sprint HD available on Amazon would be a good move, in my opinion. For most folks, that's the easiest and quickest way to buy. (If I had seen the 10266-HD on Amazon at the time, Nitro HD but not Sprint, I might have bought it. My mistake in not finding it in the listings.)
The 4-star rating instead of 5 is merely out of caution, because I haven't yet used the product enough to be able to say for sure that there's nothing seriously wrong with it. It'll take some number of weeks before I'll know that my next walker will be another Drive rather than some other brand.
Here are two very minor things that could, I assume, be corrected in some future round of improvements:
The product label on my Nitro Sprint's frame, which shows the correct model number with the "HD" suffix, incorrectly gives the weight limit as 350 lbs (non-HD variant) rather than 450 lbs. The owner's manual says 450 for HD.
The Drive cane-holder attachment (bought separately from Amazon, but it is a Drive product) upper part has such a loose fit where it slides over the accessory connector, and the plastic is so flexible, that simply pulling my 1-inch-diameter cane out of that upper holder makes the holder detach from the accessory connector every time (with the plastic slide deforming but not breaking). It's a wimpy sort of attachment, not good enough for real life no matter how it looks on paper. (Hint: When testing it, use a 1-inch cane.) I had to use some duct tape to fix it.
