I had the same issue. I received their kit back in January, when my health plan started offering it. I was also using a OneTouch meter, so I tested with both back to back to compare. The Livongo meter was consistently higher, and yes, usually by 20 or more points. It also uses a rather large test strip that seemed to need more blood than the OneTouch strip and it would sometimes take two or three tries to get enough for it to test. After a couple of weeks, I decided to stick with the OneTouch meter. I since changed jobs, and my new insurance no longer includes the free Livongo offer, but I don't miss it.
