Just picked up my new iTaste 134 and am having an issue with it. It seems to turn itself off every once in awhile. Neither my SVD or MVP do this. I never hold the igniter button down for more than 3-4 seconds at a time. It will turn itself off even though it has been laying on my desk, in my hand, etc. Is this some type of auto-protection or something or does it sound defective? Thanks!
