Looks good, feels good? Shakes well, keeps temperature well. Hard to clean but what can you really expect? If you're leaving protein in this for 12 hours+ then you're just being lazy! (Clean it well or you have a chance of creating a micro *ba-dum-tiss* civilization by the kitchen sink).

I usually go for a clear whey watermelon and like refreshers so thought I'd give it a go but the taste is far too sweet and sickly. After taste does taste like refreshers but not enjoyable

This thing started coming apart after a couple of washes. I put it in the dishwasher and the black paint started coming off within a few washes. A week or so later the metal covering over the lid came off. Would not recommend this one. Just buy the normal one

Very bad quality....especially the cap. Used on the third day already broken 

This shaker is a great size and works well enough. Yes, the metal part of the lid came off but doesn't affect anything! Yes, the black paint scratches off but the shaker still works great lol. If you're trying to show off the look of the shaker to all your friends then it's probably not for you. If you want a shaker with good volume and like drinking out of a metal container then this will work great!

Was great at first but beware if you use milk in your shakes as it will begin to smell very badly after a few drinks you make, tried to get the smell out but nothing has worked

Got this shaker a couple of days ago. The bottle looks really good, nice design and it keeps your drink cold which is amazing. However all of this becomes useless due to the fact that it leaks as soon as you take a drink making it useless.

Pro Metal Shaker: - It’s metal, so very cold to the touch if your drink is cold. - amazing size, and mixing capabilities.  Side note: while the lid is plastic, I’ve never once had a problem with it, nor have I ever experienced it breaking. - but if you want to be safe potentially use a blender depending on how much you fear that due to other reviews. 

The lid ring came off after using it 3 times. This shaker is made of a metal. This means the shaker becomes really cold or hot depends on what you put in. I wouldn't buy it again.

After having the shaker for a couple of weeks the plastic lid snapped and was unusable, and the paint started to chip off after two washes by hand, I would not recommend getting this shaker!!
