Unfortunately, this product has not met my expectations:
1. the light switch arrived unattached / not installed to the umbrella wiring. I ended up having to solder the leads to the switch. It now works, but the unit should not have been shipped in this condition:

2. Support bolts at the base of the unit are rusted, after only a few weeks of use.  

3. Pole screws rusted, and also have bent out of shape with only a moderate wind. 

4. plastic elbow support has bent.

It provides nice shade, and the crank is easy to set up and take down the umbrella.  But, this product is inferior, and I would like to be able to return this for another (better) product.
