To be honest, this is the very first reply I wrote, but I was (still somewhat is) reluctant to send it, because I don’t want it to look like an ad (which is not). In addition, I am not sure where to post this more appropriately – in Cyclone Cup review, or in Protein Shake Clumps.

Anyway. I use two shakers, both with static mixer, yet, unlike Cyclone, it’s not funnel, but propeller-like, which is far more compact in terms of height. Both work well, quite silent (in comparison with whisker ball shakers) – all you hear is liquid sloshing around, easy to wash (add a drop of scent-free detergent or mild soap, or just plain water), really don’t know what to add.

One model is from, ironically, Herbalife (it’s almost two decades old and I used it on my fishing trips to mix bait “slurry”:)) and another is from VP Lab (supposedly British brand). Herbalife’s is smaller, just 400 ml capacity, yet it has narrow “waist”, so it’s more comfortable to hold if you have small paws (like I do – between S and M on work gloves like Youngstown or Mechanix). It doesn’t have any additional “amenities” or fancy design, just plain shaker. From what I’ve seen in the gym, modern model is still the same design-wise.

VP Lab “3 in 1 Shaker” is bigger, 600 ml capacity, has wider “waist”, so it’s more difficult to hold in small and/or tired hands. It is somewhat similar to Cyclone in terms of “amenities” – it has screw-on bottom compartment that has smaller, removable tub compartment with two lids, one with three sections for your pills/capsules, and another for powder, which is good if you want to haul two portions of protein with you – one in shaker, and one at bottom, in addition to other supplements. Lid’s flap (one you open to drink) is quite strong to stay closed for whole day in backpack.

I never had to shake any of my Proteins, including Casein, which is generally thicker than Whey, or any other powdered supplements for that matter, more than for ten seconds. So when I see people shaking their cups for minute or two – that really raises my brow. Maybe I never used really bad protein brands that clump a lot, I don’t know, but I do not recall having a single blob that was bigger than match’s head, even with my lazy (or “energy-saving”:D) shaking.

Just for an experiment, I tried to spoon-stir ON’s Gold Whey not in water/milk, but in yoghurt (my experiments shows the less “liquid” is the substance, the more difficult it is to mix properly). Overall consistency is yoghurt-like, no dry or even gooey blobs. My instant cacao or coffee have more blobs that ON.

Not sure how much relevant this info is, given that we live on different banks of Grand Pond, but since I started to drink Protein, I used those two shakers and don’t have problems with clumps, even if I always “fought the rule” and poured liquid into Protein.

Take care.
