Amazon seems to have given the wrong information for this blender - unless this is not the same model as sold on Argos and various other sites? Because although Amazon have stated that it has 2 speeds and that it is rechargable, Argos give the details as:
Features anti-splash guard, angled blending blades and wall mount bracket.
700 watts.
5 speeds.
Turbo button.
Stainless steel blades.
Number of accessories 3.
Accessories include: balloon whisk, mini chopping bowl, blending beaker.
And if it is the same model, it is NOT rechargable but runs directly off the mains! Had I known all this before, I would definitely have gone for this one (mostly as it is so much cheaper!) rather than the Kenwood HB724.
