This spreader was really a great price and I loved the rubber wheels, so I bit. The final product is great, although I haven't actually used it yet. The wheels are large and rugged looking, but will require additional air pressure. The bin is heavy plastic, the spreader wheel is heavy plastic, the control lever is heavy metal, as well as the axel and frame. The bad part is the assembly. It is quite complicated and difficult to see and the instructions are hard to understand. I have mechanical skills and assembly experience, and I had a hard time with it. I would recommend you buy it in advance of you using it so you have time to put it together. I included a picture of the tools you will find helpful. It might help to take a picture of the assembly and enlarge it on your phone. It took me a good hour and some to accomplish. I think the final product is worth the effort. You WILL need an 8mm wrench and socket, a 10mm wrench and socket, a phillips screwdriver, an air pump, and a rubber mallet.
