From Ted M a poster on SI: Thanks for the post about Smith's approval for its portable device. Questions: 1. Is it now on the 'approved' list? The PR didn't say it is. 2. How is approval for portables different than approval for bench-tops? 3. What is supposed to happen with the portables that expire at the end of June? Are they to be replaced by other portables, or bench-top? 4. Why isn't IMSC's portable being tested with the TSA? 5. Why is all this so confusing?
