I had tons of issues with the unit when I first received it. This was my first blood meter and the learning curve was steep. My meter wasn’t reading properly and I couldn’t figure it out. I burned though tons of test strips learning how Tobias it without success. The “customer service” basically just sent FAQ links to solve my issues. I wanted to return the meter, but found out I cannot!! This wasn’t clear, or I wouldn’t have wasted my money. So I have a $90 meter that isn’t consistent, I’m almost out of test strips and I can’t return it!! So i either toss it in the trash, or spend more money to test my blood and have zero confidence the numbers are accurate. Just an all around poor experience.
