Here's what I purchased this month. I used it once to trim the hair around my cat's paw pads. The second time, my cat was scared by the sound and ran away, so unfortunately, I had to give up using it. The third photo is a picture of it when the power is turned on. The LED display shows the remaining battery life and a light turns on. Blade width: 9mm Power supply: USB charging Noise level: 50dB
