FORMEShaker 700ml - Stainless Steel Protein Shaker - Double Walled Vacuum Insulated - Cold and Hot Drinks - Silent Shaker - Leak Proof - Fits Cup Holders - No Built-In Storage - Charcoal (Charcoal)

Easily the best shaker I’ve owned, having gone through millions. Looks incredibly sleek, mixes perfectly, doesn’t leak, and the silicone base is a lovely touch. The opening is a tad narrower than what I’m used to but that’s fine as you just use half scoops instead - it’s really not that much of an inconvenience. Haven’t made full use of the vacuum insulation yet but it’s good to know it’s there. Easy 10/10 for me, would definitely recommend!

Positives are that it will keep water chilled all day and keep hot drinks warm almost as long. It’s a good looking and very tactile bottle but the opening does make mixing a bit of a challenge, so we’ve ended up adding the mixed shake to the bottle rather than mixing in the bottle, which kind of defeats the object. Great looking bottle though.

Just so you know, I review products for Amazon, so I did not pay for this item. Having received it, here's what I thought:This went on holiday with me, it did a great job of keeping my chilled water cool all day! Really nice touches on this too, like the volume marks inside.I did make a shake with it and the 'whisk' insert worked well. about 20 seconds of shaking and it came out smooth. It explains how much you should fill it to get that to work well.I had no problems with leaks at all, I found it easy to know when it was closed and had nothing escape.The packaging was fully recyclable, with no plastic on the box, just a single plastic bag with a PET number on it.I very highly rate this. Excellent work.P.S. The photos are of a used one (after being on holiday), it came out immaculate when it arrived.

The bottle feels solidly made, but unfortunately as the bottle opening isn't wide enough to fit a standard protein scoop, it isn't actually any good for what it's designed for.

Stylish and Robust Vacuum Insulated Protein Shaker that simply works fantastic but wow does it look great! This is an very well made product! Very well made and super tough, robust and for myself keeps cold drinks cold and warm/hot drinks hot!This is a 700ml bottle that can be used more than just for protein drinks although it is intended for that function and comes with all the kit to make and shake protein drinks with but I found that I simply used it for all my cold drinks as it kept drinks cold longer and tasted better than my other bottles.As this is a vacuum bottle made of top quality materials you can give this a good clean between uses and also it is easy to clean and stay fresh for usage. When you take this shaker out of the packaging you know this is just going to be a fantastic product bar non and or better than others out there.Truly happy with this purchase and daily usage and cannot recommend this shaker higher than 5 stars or I would.

The Forme protein shaker arrives well presented in a simple but stylish cardboard package. The quality of the bottle itself doesn’t disappoint, with a lovely tactile charcoal grey finish, anti-slip base, “silent” whisk and two-piece leakproof lid.The 700ml capacity is just right for me - it fits my car cup holder and the bottle cage on my bicycle perfectly. The double-walled vacuum insulated construction means that your drink stays cool (it hot if you prefer) for a decent length of time.Priced at exactly £30 at time of review, it’s not inexpensive - but the quality of construction makes this seem like a worthwhile investment.

Looks great and seems to be made of good materials, but leaks. Shame really as it’s by far the nicest looking and most discrete shaker I’ve found.

I am not a fan of the typical plastic protein mix shakers that have the rattling ball in the bottom to aid the mixing. They are noisy in use and being plastic, they do tend to discolour and hold flavours if not careful. Seeing the new Forme Shaker here, it looked to get around both of my concerns, being made from stainless steel and having a mixing frame at the top that doesn't move when shaking.The main unit is a solid stainless-steel bottle that has a vacuum shell. This really does help keep drinks cool for hours (can also keep them warm but not for as long). The powder coated exterior has a textured finish that makes holding it easy and the vacuum shell keeps the temperature of the drink inside away from the outside.The real change here is the mixing frame at the top. This breaks up any protein clumps as you shake, as well as giving the shake a creamier finish. One thing I did notice is that the shake mix needs to be added once there is some liquid in the bottle. If it is added first, there is a tendency for some of the mix to stick around the base and not mix thoroughly. Also, the top is quite narrow, so care needs to be taken adding the mix into the bottle.Overall, though, this is a great bottle that does what it sets out to in a very efficient way.
