I've been using a Synology DS712+ since it came out (2011 or 2012) and have really enjoyed it. Now I have a DS718+ for home use and am administering a couple more Synologies for various charities I help, including a DS920+ I'm setting up now and testing with DSM 7.0 Beta. I'm also working hard at getting fully independent of Google services. Thanks to Synology, a big part of that is done, since we can now be our own "cloud"!
