The Bellina is a fantastic lithium ion clipper to upgrade to. The benefits include faster charge time, cooler battery, and longer battery life. It also has everything you would expect from a Wahl clipper - precision blades, powerful motor and quality build.
The Bellina can be used cordlessly, or plugged into the mains if the charge is running low. The unit has an LED charge indictor to let you know battery status, and an audible tone to indicate start and end of charging.
