I'm just getting acquainted with my new G10 that I received a few weeks ago. The delivery was quick and the delivery person delivered just where I wanted it in my home. The written instructions were very helpfull in getting it up and running. Getting it connected to my phone via blue tooth was a bit challenging for this 88 year old but with your additional writtten instructions, I was able to get it loaded on my i phone. Thank you. I just have a few simple questions that I would like to ask a live person and have requested a phone call several times over several days. Much to my disappointment, there has been no response. I'm beginning to wonder about the "exceptional service" that is stated in the email I am reponding to. There was no problem getting to talk to a person when I was ready to purchase. This is my only reason for rating Hypervibe as a 4 stars rather than a 5. I am still waiting for that phonw call!
