Good basic shaker, has no measurements on it however. Had to mark the level I need myself with a vivid. Spiral ball mixer works well.

Can't have one without the other.

A must have if you're about to embark on a journey in Optislim shakes, work well with very little spilling. Highly recommend.

Excellent Shaker

This shaker was perfect for use with Optislim shakes. Even had a filter of sorts that allows you to make your shake with ice cubes but prevents swallowing the ice as you drink it. Great product at a very reasonable price.

Good shaker for the price.

Glad to finally find a smaller shaker that wasn’t more expensive than the larger ones. Decent quality, but make sure to not forget the stopper in the lid as well or you’ll make a mess!

Great shake mixer!

I bought this a month ago and love the way the slim shakes mix so well, no more lumpy bits. Can highly recommend it. Would be great for smoothies too. The secret is probably the insert inside that ensures a smooth shake. Not all shakers have that, thankfully this one does!

Have always liked these shakers

I’ve had a few of these over the years I’ve always liked them and now I find them to be even better with the metal spiral added inside. I’ve seen a lot of people complain about them leaking when they shake them but I find that shaking them side to side rather than up and down eliminates this problem and everything still gets well blended. I think shaking up and down is a bit of overkill and from past experience it does make the shaker leak but doesn’t make the drink blend any better.

Leaks - Avoid like the Plague

A fantastic shaker if you want protein shake sprayed all over your kitchen walls and floor. Designers tried to be clever by incorporating a straw opening with flip-top lid, not realising the more extra openings the higher the chances of leaking. I advise trying to find one without a straw portal.

Not great

Not happy with this shaker. I do like the metal ball but it's very hard to read the measurements. My biggest issue is that the lid leaks. There's no rubber seal inside that could easily prevent the leaking.

Shake before you shower

The first one i bought was larger and had a great seal. This one is halfthe size it has a extra disc that sits inside the lid, and if you dont use it you will be covered in your shake. The seal is no wear as good as the original.

rubbish

recently took delivery of this item with a view to using it with diet shake products. Unfortunately the lid doesn't seal properly, causing leakage when the shaker is shaken. I guess that's what I get for going with the cheap option
