FlasKap Madic 9oz Drinking System: Compatible with Most 30oz Tumblers, Mixed Drink Well Attachment, Leak Proof Lid

Ever since I saw this product first advertised on social media a few years ago, I thought wow, what a cool concept. I now own both the Madic 9 (holds 9 fl. oz.) and this (the 6 oz.), along with an earlier version of the 6, before it was called "Madic." I've taken mine to many an outdoor venue, such as waterfront culture & music festivals, parades, street fairs, backyard BBQs, Fourth of July parties, you name it. Works great for tailgating and free public sporting events too... pretty much anywhere they won't inspect your stuff for "contraband." The Madic 9 is great, but 9 ounces of liquor is a LOT, which is why I needed a smaller one. I wanted to replace my old 6; the stopper had a tendency to leak. (Full disclosure: I left liquor in it for far longer than I should have, which may have damaged or otherwise degraded it.) The 9, which fits my 30 oz. Beast tumbler, may be better for longer, all-day events; but for a shorter time period, the 6 (with my 20 oz. tumbler) works just fine. My go-to is to fill the cup with ice & lemonade, and the FlasKap with vodka, but I also enjoy Coke or Sprite with some Fireball whiskey to add in. Sure, concealing bottled or canned beer in an insulated, individual keeper is fine, but that's just _one_drink_ and it's mostly water. I won't carry 6 of those with me– too heavy, bulky and expensive, plus moving around will jostle the contents and lead to a sudsy embarrassment. Besides, it won't stay cold for really that long; a vacuum-insulated tumbler that keeps ice frozen for hours just makes more sense. Carrying my traditional hip flask, hiding it, looking over my shoulder, pouring it into a cup... that just feels sleazy. The FlasKap fills easier, and I don't have to deal with a funnel and the inevitable overpoured mess. I freakin' love my FlasKaps. I want to buy one in each size and every color to give away this Christmas.

Bought this for a white elephant gift, but ended up getting it back. And I am glad I did. This works effortlessly with my Yeti. It fits a good amount of liquor and you can control how many pumps of the good stuff you want in your drink. It's great for on the go when you want to have a couple of mommy drinks, but don't want to tow around a giant bottle. The best part is you can't be spotted by the fun police. This does not seal the cup, so turning it upside down or laying sideways in the cooler.

I got this for my wife because it’s a cool idea and very useful. She loved it, until a month or so it started leaking. So now it’s just taking up space because I don’t want to throw it away. Maybe I will. ++Updated my review, the company sent out a new cap, excellent customer service!

Bought this as a gift, have not heard of any complaints from my buddy. He stated it works fine and he uses it frequently.

Great gift!!! Easy and so fun for those friends in your life. Dishwasher safe and travel friendly!!

I am so excited about this product! I saw the reviews that it didn't fit other tumblers, but it fit my large YETI and my large, metal insulated Tervis Tumbler no problem! I did notice that when filling, I had to turn it slightly to the side to release air bubbles so I could continue filling it all the way up. I also noticed that when I push the plunger to dispense, I have to again tilt to the side to release air bubbles or it won't dispense any liquid when I press the plunger again. I am giving it 5 stars because it is genius and I can make it work, but I hope they perfect it per the other reviews I read. I have not used it with alcohol yet, I tested with water, so I may have an update at a later date. I didn't notice any leaking as mentioned in other reviews, but we'll see!!

Update: The company reached out to me regarding a replacement. I was surprised to hear that they were giving me a replacement free of charge despite having had the product for 10 months before breaking. Raising my review back up due to customer service. Original Review: This was great for my pregaming sessions. Fill the cap with my favorite whiskey, then the tumbler with ice and out the door I go. I drink my liquor straight, so this was perfect. It's also great since I already count my shots. However, about a quarter of my friends saw the liquid in the cap and knew what it was. Unfortunately, this means it's not as incognito as I had hoped. Now on this day, 10 months after purchase, the spring loaded cap broke. I would have continued to use it of it had lasted longer. Unfortunately, due to the 2 reasons stated, I won't be purchasing again.

Bought for a friend for her birthday. She loves it.

Drink up

It works good and cool way to sneak in some booze, but hard to clean

Great product! What a fabulous idea. Worked out a little expensive shipping to Australia but absolutely worth every cent. Fits the 24oz Yeti Rambler perfectly!

This thing is great! I love it, you can go anywhere and no one has any idea you’re drinking. Perfect for festivals in the park if you feel like having a few. I’ve used mine more than a few times now and I’ve never had an issue. Highly recommended 🤙🏼

Tik Tok made me buy it. Love it!
