The scale fits well into the hot shoe of my Panasonic Lumix DMC-FZ200, can easily be pure and able to remove it and sit still firmly. The display is up to about = 0.15 - 0.2 degrees horizon exactly (which is not bad for a Aufsteckwasserwaage). Some construction tolerances, however, lives, who need not be beding by the spirit level. Levels of this size and price range can be difficult to produce accurate. If I think also a matter of luck whether you get caught one that accurately measures. My fit, lucky. For that man must have happiness a star deduction.
