Full disclosure: I got it free as an Amazon Vine reviewer. But just because I did not pay for it does not mean I won't tell the truth. So here goes.Pro:1. True to its name, as a special purposed stair climbing cart, it is excellent. I can effortlessly go up and down stairs. And with its 3 wheels set up, I can even rest it mid-climbing with ease.2. For its size, it is very lightweight. It is about at least 1/2 if not 1/3 the weight of my current convertible cart. All parts are aluminum. So very easy to lift it and carry it around.3. Since it does not have too many moving parts and sans folding mechanism, no rattling either.Con:1. If you think IKEA is bad, this is far worse. Instruction is very basic. Thankfully, they included pictures. So I can deduce what to do combing both. Even so, one has to have basic mechanical aptitude to put it together. Oh, and tools. 1/2" socket wrench is a must. Those of you who can't install your own faucets/toilets/oil change/IKEA/etc... need not apply.2. After about an hour getting it installed properly, I was surprised at its size. See the comparison of the cart vs my current one for size comparison. A bit bulky to my liking. If it can be folded somehow.. Then again, I am sure that would compromise its weight capacity and complexity/price.3. While it is very good at climbing stairs, on regular pavements, it is not nearly as good as my semi-pro convertible cart. The small wheels WILL get stuck by uneven surfaces that the big wheeled counterpart would not.4. Lastly, the foam on the handles are nice. But they will not last under UV or wear. Hard plastic would have been much more durable.
