Mr. Pen- Shaker Bottles for Protein Mixes, 28 oz

Good quality does what it’s supposed to. I really enjoyed the black color of the lid and cup. It mixed my powders up well it was a perfect size for me. Stable cup wasn’t tipping over and was nice dishwasher safe.

After having it for two months is was really cheap no leaks or anything. It works really good. I use it for the gym three times a day for different liquids. Just what I wanted for the price. 8/5/26.

I am very happy with this shaker bottle. I have been using it daily for 6 months or longerand it has held up like a champion. The seal holds well and It is a fairly large shaker bottle, but still comfortable to hold. I have arthritis so that matters. I prefer the black color, because my herbal mix looks kind of ugly. LOL There was a sweet little note in the package from the distributor, which I think is very thoughful.

★★★★☆ Great shaker bottle, but cap could be improved This shaker bottle works well for mixing protein shakes and pre-workout. The stainless steel whisk ball does a good job breaking up clumps, and the 28 oz size is convenient for workouts and everyday use. My only issue is that it does occasionally leak. The lid closure is not as secure, and you have to hold it closed when shaking. I have to make sure I am holding the cap closed securely when shaking it, which can be a little inconvenient. Other than that, it is a durable and useful shaker bottle that gets the job done. The cup does come in a variety of colors, it is a cute quality!

Bought this item as a gift, it was liked. The lid closure, and ease of use was great. I recommend the purchase.

Easy to clean, mix well and do not leak.

After doing a bit of product comparisons and reading reviews, I recently ordered the 28 oz Mr. Pen shaker bottle and a 25 oz BlenderBottle Sport Sleek insulated stainless steel shaker bottle (which was about 3 times the price at the time). I have used both several times now, making the exact same shake each time. My initial concerns for the Mr. Pen shaker were 1) that it might not mix as well since it didn't have a rounded bottom like the BlenderBottle had. This proved absolutely not to be the case. The Mr. Pen mixes significantly better, maybe it's the different shape of the shaker ball or maybe just the extra 3 oz of space in the bottle, but hands down Mr. Pen wins. 2) The lack of the locking lid like the BlenderBottle. This proved to be not an issue. It snaps closed solidly and easily. 3) Not being insulated. Also ended up not being an issue for me really. My advise, at a third of the price, go with the Mr. Pen version for sure.

This thing leaked from day one and never got better. I was bummed, because I really wanted to carry this around in the gym with me to every workout station. Oh well, I guess I'll stick with a cheap bottle of water for the time being and look like a loser.

Lovely! Love the color and price! Very pleased! Thank you.

This cup works great! The shaker ball is amazing mixed up my powder super fast and no leaks! I love the mustache sticker and the note that comes with it!!
