I use the Freestyle Optimum Neo.
There are a few reasons for this
- It is small. I don't want to hike around a big meter.
- It is easy to use. Put in the test strip, give it some blood, 5 seconds later the results are displayed.
- It doesn't take much blood.
- It is pretty robust. To take up less space in my bag/pocket, I chucked out the case years ago so I need something that I am not afraid of breaking
- It measures both BG and ketones (with different strips)
- The customer service from Freestyle is good. They replaced it when I complained there were some fixed pixels on the screen
- It is easy to upload to Diasend. You just plug in a USB cable.
It's not perfect
- the test strips are individually wrapped in foil. Some people complain this makes them difficult to get to. I just think it's extra waste
- changing the time is far from intuitive. I travel 5 or 6 times a year and struggle to change the time when I do. This may not be important but to correlate the readings on Diasend, I need my meter and pump to be on the same timezone and I need to change my pump to ensure the different basal times are correct.
- It does not calculate insulin doses. This is not a problem for me because my pump does it with far less button presses than the Insulix meter does.
