Olympia Tools Foldable Push Cart Dolly 4pack

I felt compelled to write this review because I looked at reviews here before I purchased, which almost caused me not to buy. This is one of the cleverest-designed products I have ever come across. I bought this cart because there are times when my wife needs a portable cart for her work, and she found that the portable cart I have is too heavy for her when she is by herself. This cart is light, easy to handle, and will easily carry 300 pounds and just a bit.One of the best features of this product is its easy assembly. No tools are required, except for a cutting tool to remove the tie-wraps that hold the wheels. Speaking of wheels, they are the true genius of this portable cart. Before it arrived, I was curious about why all four wheels were allowed to rotate. The answer is simple-it's for easy installation. By allowing all four to rotate, you can just snap them into place; no nuts or bolts are required. It's a breeze to set up.The wheels' installation takes two minutes. I have seen reviews with comments that the product is so cheap that the wheels fall out. The wheels do not fall out if they are installed properly.There is a snap ring type of device at the top of each wheel; when you insert the wheel assembly into the hole in the bottom, as you push the wheel into place, it compresses the ring at the top. Just before the wheel is fully engaged it feels like the wheel is installed. It is not properly installed at this point. You need to push the wheel in so that the ring at the top moves beyond a shoulder. Once you do this, you hear a click as the ring expands so that the wheel can not be removed.You don’t need to be a bodybuilder to generate this amount of force; you just need to be aware that a click must occur. This is a great cart for people who want something light and easy to carry.
