2 pk TSF 25 oz Stainless Steel Mixer Shaker Cup Bottle

Got this in the mail and everything seems good. I don't mind that it's non insulated. it's sturdy enough and easy to use, nice design and colors. I cleaned them out before use. One will be for home, and the other for the gym. I tested them out already, and there are no issues. For the people that experience leaking, if you tighten it too much or the seal is out of place, it may leak as with any other rubber/silicone seals.I hope to have these with me for years from now. I had a plastic GFUEL shaker, and the top flip spout started breaking apart. I'm hoping that these will last much longer. Also, with stainless steel, it still can collect scent, and stains- it's resistant, but not completely stainless, so the best thing to do is soak with a full cup of vinegar and 1/2 cup baking soda mix, and fill the rest with water. Add a little, few drops, of Dawn or other good dish soap if possible. Soak for full 24 hours every month to cut down on smell. You don't need to use hot water, either.I usually try to keep away from hot liquids in shaker cups, as any plastic parts may expand and contract, warp and may not fit with the rest of the materials. Also, when you're using these, it's best to put the liquid in first and then the powder, as it may stick to the bottom if you do it the other way round.Other good care that I do with these is wash them out after every use, or once a day at least if used multiple times a day. Taking the ring out to wash underneath at least weekly is important, as well. Once anything grows under there, it's easy to forget and it can grow black mold. Then you've hit a roadblock.

Had to throw.one away almost immediately due to cross threading. Lid was stuck on it tight.The other I am still using for several months now

Simple shaker cups, not much can go wrong. I like that the mixers are built in to the cap - not likely to misplace them!

Absolutely terrible quality do not buy this cheap product, the metal is cheap but the plastic is cheap and overall is a terrible design mold can very easily accumulate in the top and anytime you drop this product it will explode all over the floor .

I like the cup, but the problem is that I only have one working one. The second one leaked immediately upon use, as if not properly constructed. I reached out to the seller with no response. I would leave 5 stars, if I had two working cups and a response from seller.

Within few days the color was peeling off so you can see metal/tin, whatever it's made of. Disappointing. I kept one & gave one as a gift. Same thing on gift one. Kinda embarrassing.

sadly the top is still plastic so they are not all steel but overall happy with them after a few weeks

Great shaker for the money. Absolutely love that the lid and aerator are one piece. No more looking for which one goes to what shaker
