D'Addario Eclipse Rechargeable Clip-On Tuner PW-CT-27

It is a chromatic tuner with a full-colour vertical display on an extra-bright LCD, and D'Addario lists it for guitar, bass and ukulele. The multi-swivel mount lets you clip it in front of or behind the headstock and angle the screen towards you, on right- or left-handed instruments. The colour shows where the note sits: red for sharp, blue for in tune and yellow for flat. Calibration is adjustable from 430 to 450Hz with the arrow buttons, and the tuner switches itself off after 10 minutes to save charge.

While it charges, the middle LCD segments scroll from left to right; when they stop scrolling, it is fully charged. D'Addario's manual rates the built-in lithium-ion battery at 3.7V, 120mAh, and says to keep the tuner away from children.
