This blender is awfull, It is really fiddaly, You have to line up the inside post than attach the blade then attach the hand piece and lock it into place! Not only is it a bit tricky to put togeather, but because of the little bits it's hard to store, if you loose the inside post the whole thing is useless, what a pain, when all you need is a click and go system!
I have used mine six or seven times and now it will not lock togeather, so is no use at all... I am hawever really chuffed as I can now buy a good one, probably for a lot less money, save your cash ladies and gents, give this one a miss!!
