sounds really good but this puts me off slightly
Power comes from a proprietary lithium-ion battery with ID-Security feature that prevents use of counterfeit or third-party batteries
not the proprietary bit, but the rest of the sentence. 3rd party batteries made by Hankel and energizer are, imo, and experience as good as the manufacturers ones and usually a third the price. that end sentence seems like they are forcing you to use their batteries which will no doubt be quite expensive.......
