After 2 uses the blender leaks when shaken to mix the components. The bottle may be pretty but its primary purpose remains still to be sealed ... I do not recommend.
The wire ball is ok but I mostly use my sccm to electric blender. The actual cup is excellent and I use it to drink my juices. It is excellent quality.
All my protein mixtures, whey or casein, are mixed in the best way! I take it in my bag in order to drink protein After training, and do not afraid about my stuff, this shaker never leak!
