We have about 40 each of the genius and Pro3000. We had 40 Pro1's, quite simply the Genius was better, then the nice man swapped out all the Pro1 for Pro3000 and they seem about the same as the Genius. The Genius calibrator is **much** better than the Braun, we had quite a time getting a Braun one at all, then when it came it had a French plug, but now we have one with a trusty 13A on it. Since Braun give us the tymps, and the calibrator, it makes you wonder what they get out of it, perhaps there's a lot to be made on the consumeables. Yes I think that must be it! God knows what the Genius calibrator costs them, I know it cost us nothing. Still our nurses try to keep costs down by not using the tips. Why do tymps always come in with the complaint of reading low? Try telling a nurse that the window has got a great lump of wax on it!
