Dislike…
Thin plastic they used to protect the screen… it scratches just going in and out of the full case!
The rather dim strip light that used a cheap yellow LED not a white one…
The crappy case that doesnt really fit the strip bottle inside it…
The meter not always going on automatically on strip insert…
The software reports arent as nice as OT or other meters
No way to enter carb calcs even if just to remind you how many carbs you corrected for
No way to enter insulin injected (bolus)
Like:
The display size and clarity of text/numbers
The reminder feature… Its an alarm that goes off after x period of time after you take a BG reading… great for checking for a correction 
The software is built in
