I have the optimum neo and I like it - that being said, I'm 10 weeks diagnosed and I haven't anything to compare it to. My consultant was impressed that the nurse gave me this one though, he said it was a good one. The only thing that annoys me is that if you do not apply enough blood (it doesn't need much but as I said, I'm new) you get an error and have to start again with a new strip. I'm getting better at this though!
