No building instructions and a heavy rubber odor that lingers for a few days. Keep it in the gara...
I am a 74 year old widow living in a two story house. I bought this stair climber hoping it would help me lug my suitcases up and down the stairs since I travel frequently. Took me a while to figure out how to put it together since it didn_ come with instructions. (You might want to type up some for novices like me.) Once it was built I tried it out. It works great!! The first thing I moved was a 62 lb dresser! The wheels moved perfectly going slowly up the stairs. I used the nylon cord that came with the cart to tie it securely to the frame of the cart. I got it up the stairs and into the bedroom without any help! It is definitely worth buying. I am going to put this cart to good use.
I have been wanting something like this for a while and finally decided to buy it since I have to carry boxes of books up stairs every day. This works exactly like I expected it would. Goes up stairs very smoothly and it is easy to use the included tie down/bungee to keep boxes from sliding off. Loved this so much, I plan to buy another one for my daughter in college.
Got this for the new townhouse, there are many steps and columns.Great product very sturdy and durable. Is the factory on the beach? There was lots of sand and what is that smell? Kinda like Armor-all and lemon pledge. Thought it would disapate after an hour or so but 2 days later it is still not allowed to be stored in the house. Great! Now that nostril piercing smell is on my hands it follows me everywhere.
