The problem with a review like this is the small appliance market is often changing. Your 4th choice Russell Hobbs Desire 3 in 1 Electric Hand Blender, is no longer sold on Amazon or on Russell Hobbs own site. Your 3rd choice is also no longer available on Amazon or available on Kenwood's own website. It is better for a consumer to look at available blenders then seek a youtube review rather than the other way around.
