Mr. Pen- Shaker Bottles for Protein Mixes, 28 oz, 2 Pack, Red and Blue, Protein Shaker Bottle with Wire Whisk Ball, Shaker Cup

Great shakers but do not put them in the dishwasher. I didn't read the instructions that came with the containers. And one of them cracked. My fault. The are very nice. Love the colors, great product. Mixes up our protein shakes really well. No clumps.

The shaker is light enough color to see the liquid inside. Comfortable fit in your hand. Top screws on with no leaks. Best part they are easy to clean by hand or in the dishwasher. My grandkids constantly borrow them for the gym so I have to purchase new ones frequently. Linda KERZAN

I take my morning smoothy to dog park with me so I needed a cup that wouldn't spill or shatter if knocked off bench by an excited dog. this cup is amazing. We have a couple new lg puppies at our morning gatherings. These cups got a work out the very first week. I mean several crashes daily. I don't have any of the lid issues others posted. I'm 65 and have no trouble opening or snaping the spout closed. It's a secure twist top. I like the size and the shaker keeps everything mixed. I onle wish it came with a strap to carry. It took me a few days to make my own. I rinsed out with soapy water when I got it and drank ice water out of it to see if there was any unusual taste. There wasn't. I go to park and river regularly so these cups get used a lot. I even ordered another set to make sure I wouldn't have to switch when these wear out. which I don't think will be any time soon. I'm very happy with these shaker cups. thank you

Really loud the product and they sent a handwritten note saying thank you for shopping with Mr. Penn. It means a lot to us yeah that seeing that card that means a lot to us too. It's really very good. The product is good. I would recommend this to anybody I would say because you know what of eight dollars you get two Shekar bottles and that two with this quality it's a steel.

Perfect beverage to avoid spills at home or on the go I keep water in one and coffee tea or lemonade in the other Great for mixing. Cap is extremely tight

Lovely the bottles are made well I like the shape of the mixer made it easier to blend my mix I got a nice thank you card that was sweet and make me smile I highly recommend!

I drink breakfast shakes in the morning and it takes for ever to get it all blended to gethere .. But now in 3 min.s I am done and ready to go . it's so much ezer than before ....

Plastic lid flip closure is not very tight. Doesn't leak but will give it a few weeks try. The little metal whisker inside is not a ball type; takes a while for powder to mix together with milk. Use for protein shakes. Measurement lines not visible. Just run of the mill shaker. Nothing spectacular.

I was so frustrated with the company shipping this product and with Walmart. I never received the product and I never received text or email notifications for the progress of the shipping/delivery. I had to go and track the order myself and the tracking kept changing as to when it was going to be delivered. Eventually it said it was delayed even though at one point it said it was out for delivery. After almost three days of no updates, I contacted Walmart only to be told that I would need to request a refund because it most likely wouldn't ever be delivered. I am so disappointed with this order and I don't know if it was the company, Mr. Pen, or Walmart who dropped the ball.

If I had to purchase this item again, I would not. The issues I had is the product did not completely seal. So, when I go to mix my liquid, it goes everywhere. Also, they had a weird smell. It was like oil and no matter how many times I washed them, even in bleach, the smell remained.
