I originally received this product for free for my complete honest opinion after testing and reviewing this product. My mom wanted to remodel her bathroom which this came in very handy for that project. We installed it with the instructions that it came with which were very simple to read and understand. After it was installed we gave it a test try and were happy with the results.  So far everything is working properly don't have any complaints whatsoever it runs the water perfectly fine for us. I would recommend this product.
