I purchased this dolly with a stair climber because my previous dolly did not have one and one that I purchased off of another website came two times broken this one was very affordable. I was very skeptical about its quality, but when it arrived, I was very surprised I feel like this is the best deal, especially for those like me that do deliveries for apps where they may give you something big or heavy and you have to go up the stairs. I have use this so far to carry up cases of water and sodas, four piece outdoor table set and two TVs over 60 inches now I would like if the handles that extend may be extended just a little bit longer but otherwise this is a great stair climbing dolly and I do recommend this for anybody who works off of the apps Anything like Walmart Home Depot this is the perfect stair climbing dolly
