I've used a lot of different shakers over the last 10 years and most of them fall into one or more of these categories; constructed out of a plastic that absorbs odours so well that you pretty much have to designate it to one type of powder, which usually means you can forget doing your blended shakes in it. Others have ridiculous little nooks and crannies where powder settles and forms these stinky little lumps that are impossible to get out without a fine, sharp instrument of some sort and, unless you wash it right away, start to smell your shaker out. Or it has some ridiculous slogan on it that lets everyone around you know you wish you were born a gorilla or some other kind of large animal (no shame, we've all been there). This shaker, is perfect. No useless, flashy ridges and design patterns that look like a little space shuttle, it's easy to wash, and lets everyone know I'm now happy being ripped AF, and don't wish to turn into a hairy, sabre toothed beast with acne. Whatever plastic they've used, just does not hold onto smells, and I use an immersion blender to blitz heaps of stuff in that thing. Only downside is, it's not dog proof, the little hairball shredded the top of the cup and since I've been losing muscle by the second. Hence why I'm leaving a stunning review in the hopes the folks at NUTRITION WAREHOUSE hook your boy up with a free shaker that I'll probably buy anyway because it is so **** good. Can't blame a guy for trying, right. Do yourself a favour…
