I can't compare it to anything else s this is my first cgm experience. But it's been extremely useful. Can't vouch for its accuracy. i did check it once against blood-from-finger, and they were in sync. Whether that remained throughout the time period I'm not sure.
My unit did fail 1.5 days early, however. No knocks. Held on with included patch, plus 3rd-party waterproof patch. Just stopped recording data and told me to start a new sensor.
If you ever find yourself in a position where you have to self-fund, please buy direct from them. Not only do they offer the best price, but they will only replace faulty sensors that are bought directly from them.
