The Liveryman Plus clipper is quite an innovation amoungst clippers. The internal battery is undoutably the best feature as it'll give between 1.5 -2 hours clipping time itself and that's at a blade speed of 2,600-2,700 stokes per minute. The blades used are the 'snap-on' type that are also used with Wahl, Andus & Oster clippers and the one supplied with this package is the narrow 1.6mm blade.
The clipper can also be run with a battery pack to give it an additonal 3hrs running time. The Lithium polymer battery has no memory so it can be recharged without affecting it's lifespan. Please note these batteries are the same that were sold with the previous generation of Harmonies but with a different connection so the older Harmony batteries will not fit
