The GXWH70M is of excellent performance and value.  This amazing device filters the water and the additional app installed in the phone allows for excellent up to date information on my house needs.  This product is compact, easy to setup and install and provides an added sense of comfort to my home needs in relation to filtered water.  I am amazed at how this product connects quickly with the GE phone app to produce excellent results.  I highly recommend this product.  The instructions are clear however my only recommendation would be to have a video link added to be able to see the full installation as my husband searched for a YouTube video to install it correctly.  Other than that, this product is a must have for every home.
