The doctor gave it to me for free because as an uninsured person, she couldn't prescribe me strips for the Accucheck instant that I had.

And since it was free, I decided to use it. The pen with the needle hurts a lot, while I never had a problem with any other device. But the measurements taken simultaneously for 3 days from the same finger with the Accucheck instant and this controlbios td-4277 had huge differences. On the first day, the controlbios was 7 units higher, on the second day 2 units higher, and on the third day 32 units higher.

Certainly, since they were taken simultaneously from the same finger, one of the two doesn't work well, but the only solution is at the end of the month when I have examinations at the hospital, to test both machines at that moment to see which one is more reliable.

Positive: Large and bright screen. The plus is the type of battery it uses. You no longer have to deal with CR batteries...
Negative: It does not have a punching machine.

Prices much lower than the actual ones. I used it by increasing the measurement by 20-25% to get closer to reality.

The controlbios meter is very good and meets my needs. I have recommended it to 2 friends and they were satisfied. The software they gave me for the computer is also very convenient, and I have a complete file with my measurements.
