This blender is super easy to "assemble".  The canister clicks into place with a 1/4 turn.  It is very secure.  The lid snaps into place using the handle to tighten and seal.  The release button is a great touch.  I use this every single day for smoothies.  I normally use about a cup and half of ice cubes, and the three blade system chews through them no problem.  Along with frozen fruit pieces, herbs and vegetables, I never experience a chunky smoothie.  I have used this to make a blended soup, I can make it smooth, or still have some texture.  The Auto-iQ buttons make smoothies, ice cream and crushing ice easy.  There is no guesswork.  It seems like a workhorse--I have only used this for about two weeks or so, maybe a bit less.  Very well made, very easy to clean.
