Review on 🔵 Premium Leather Magnetic Case for AliveCor Kardia Mobile: Protective Travel Case with Keyring - Blue by Dewitt Graham

Small and useful device. Looks good, especially with the case that is sold separately. I bought both and loved the convenience, looks and portability. However, it always takes some time before it works. You have to fiddle with this thing until it (magically) starts working. I even changed the battery to make it work. but no, the thing starts to work when it wants to, not when it has to. This uncertainty kills the target.
