Blender in your hand, hardly leaks.
The bottle is well made and feels great to hold, very ergonomic. There is some sort of rubberized grips on either side of it, which feels super nice to hold. Being able to clearly see the volume measurements are great since I mainly use this for powdered drink mixes to intake more water. I haven't made any shakes yet, but see no problems in the future since the blender ball is really efficient and mixes well without having to shake super hard. It's labeled in ml and oz and holds 700ml or 24oz of liquid. This works great, looks great, and arrived really fast. The only reason I couldn't give it five stars is that it does seem to leak every once in a while. It feels like there is a teeny-tiny gap in between the threads in the lid on the back. Even when screwed on as tight as possible. I just shake it over the sink or with a napkin/paper towel wrapped around it and it's fine since it's not a large amount coming out.
