The instructions are written in non-standard English and the writer clearly had an extremely rudimentary knowledge of the language and the photos are not especially helpful IMHO.That said if you are reasonably mechanically competent you'll be able to figure out how to install this product, which appears to be solidly made, and of quality. as well as significantly less expensive than alternative products. I say this without yet having done the installation so check back soon to see if this has changed.
