I was expecting a larger screen as it looked larger in the picture. But it really doesn't matter, when I tried to measure DC voltage the readings fluctuated from -3V to 28V without touching anything. I then measured a small AAA battery at 1.5V and after the fluctuation stopped it stopped at 8V. I then measured a car battery and got a valid reading. I was thinking of returning it but then I read the seller's return policy that if it's found ok I'll get a 50% restocking fee, if for some reason it doesn't ship via regular mail I would for other provisions paid by services. I don't think you should bother, so I'll just use it to check the car.
