The best choice of Beingtrim waterproof hair trimmer

The best choice of waterproof hair trimmer is the Beingtrim wet and dry trimmer. Not just used as a beard and mustache trimmer is again suitable for using in the shower for trimming any area of body hair. With an 8 hour battery charge up the battery will operate for up to 40 minutes. This adjustable hair trimmer features stainless steel blades which are spring loaded and won't need to be continually adjusted by the user. Those who have sensitive skin will be pleased to know that skin irritation is also cut to a minimum due to the hypoallergenic blades.  What is does come with are of course the trimmer, battery charger, brush to clean ant stubborn hair of and the trimming bade oil. Again with this trimmer there is no mention of which battery type is used. Doing a search I have discovered that it uses a nickel cadmium battery.
