Honestly the best shaker I've had (and I've gone through many). Keeps items cool and NO LUMPS!!!!

Compared to other shakers I've had this one does not meet the mark. There is no mesh or 'spring ball' to help mix powders in the bottle, only a couple of angled slots at the top in the lid. When trying to use this as a shaker my protein shake was lumpy and poorly mixed. That being said, I now make my shakes in a blender and use this as a way to keep them cooler for longer because it's metal, which works just fine. The metal is easier to keep clean compared to plastic shakers. So this is very much you win some you lose some!

Leak proof  Not insulated  so it does get condensation on the cup but is way better than my plastic ones in terms of not holding that awful taste 

it's a good shaker, decent seal and doesn't need a ball. my wife is quite impressed with how wide it is, as she put her mothers daffodils in there...

Lovely shaker and very stylish. However, this does leak even when the lid is on tight. It’s such a shame as I want to use it, but, it now sits in the cupboard as an emergency shaker. 

Good large capacity and as mainly metal cutting down on plastics as well.  Mixes powders well with a good shake.  Best to wash lid by hand I put bottle and lid in dishwasher and glue that holds metal trim onto lid melted so trim now sits on but not attached, however not essential for use as it’s the plastic part of the lid that seals onto the bottle.

Very good quality and good seal on the lid very impressed and love the design!!

Looks really good and well made. It does not come with a mixing ball which is slightly disappointing.

Ver good. A bit too wide for my grip but i love them

Love thos shaker so much, the look is really nice and I've had no spills so far except for the fact that I shook it when I forgot to close the lid 😂 no problems with ot at all
