I have had a problem with my EKGraph since Sept. 14, 2019. I submitted that information to the Help Desk on that date and received a response on Sept. 16 with instructions on how to correct the problem I was having with syncing the information to my smart phone (there had never been a prior to then). The "fix" did not work and I relayed that info back to SonoHealth on Sept. 16 and three more times since then. It is now Sept. 21 and still no response. I have not been contacted about this issue since the initial response on Sept. 16. This is unacceptable customer service and it seems to me that SonoHealth does not care. I am going to get another device but not from SonoHealth.
