somebody mentioned earlier about cust service! i called vivape with just some questions..and they called back within the hour. sat on the phone with the guy for about 20 min as he answered every question i had! i have spoke with other co's that it seemed to be a bother for them to "talk" but vivape was very professional..and made me feel part of a family that just made me want one even more! cust service means alot to me..and they have won me over there..just throwin that out there..
