While the product itself seems adequate, customer service is less than ideal. It took days to get a response and a phone call was deemed inconvenient. When the phone call finally came in, it was handled decently. However, when it went back to emailed responses, my questions were dodged and NOT answered and the representative went on repeat of all the items I already understood from the phone call. I wasted hours of my time with the back-and-forth emails. The product instructions are quite involved and led to wasting a lot and I mean a lot of strips. Come to find out the strips were poorly made and not drawing up the blood sample on many occasions and giving errors which led to more waste. I took a video and was told I was doing it correctly, so no resolve there. For the wasted time and the poorly made strips, I was given $5 for the hassle. A bit insulting since I was helping you all figure out the problems with your product and I still do not have any answers.
