Keurig My K-Cup Reusable Filter MultiStream Technology - Gray (Packaging May Vary)

This K-Cup is a great K-Cup for all you people who own a Keurig. K40 machine. My new keurig 2.0. Malfunctioned, so I went to Goodwill and I saw an older model keurig(k40) so I purchased it hoping I could use my K-Cup with this older model I purchased at Goodwill because I don't like the way my coffee comes out with the pods that you purchase in the store filled with coffee because it's too weak. So I was looking in Amazon for a compatible K-Cup that fit the K40 and they showed the Keurig K-Cup that looked like the ones I use that fits my malfunctioned Keurig 2.0 so it must be one designed to fit the K40 specifically I thought So I ordered it! It wasn't until today when I went to check my mail for my kcup and it hadn't arrived yet so out of frustration and being mad wishing it would hurry and get here so I could enjoy my coffee again is when I noticed a video in the product description that I hadn't seen before so I descided to watch it and I so glad I did!So the video shows a lady demonstrating this K-Cup used with my newly purchased but much older model keurig K-40 I found at Goodwill to take the place of my newer Keurig 2.0 (very clean in pristine condition) as I watched the video it shows her pulling out the K-40 models built in holder that holds the coffee pods then this is where the video became very clear to me.... it showed her taking the Grey tab off the K-kup then sitting in the place where she took the built in pod holder out and placed the kcup into the machine! So after that I got to the part of the video where she stated "Attention Keurig 2.0 owners DO NOT remove the Grey tab"! That's when I had my wake up moment, my uh-huh moment, that's where I went wrong and unnecessary went without my coffee for a solid week I wasn't assembling things right. When they say advertise these K- cups as universal, they weren't kidding! it. I was not paying attention I guess or doing enough research. Anyways, I immediately went to work and I brewed my first cup of coffee with my new yet much older machine and let me tell you, the Keurig K40 brews a much better cup of coffee using these K cups than my newer model did. Not a joke. I give this product a five star review. Unfortunately, I have several of them kicking around so I don't need anymore do I'll return this one and receive a credit for something else but I just wanted to share this review with anyone who might be in my situation or similar to mine! Had this jcup came in the mail on time I might have not found this video out of frustration so I guess like the saying goes everything happens for a reason!FYI. for all of you who might like your 12-16ounce cup of coffee strong like I do then start brewing your coffee in 4ounce incrimints and pull your coffee cup out and put something in it's place to catch the remaining hot watered down coffee!! Continue doing it this way and with every 4ounce brew cycle to get you to the 12 or 16 ounce cup of coffee! Remember you also need to fill the K-cup with coffee everytime you select the 4ounce brew as well! This is how you can get to your personal desired strength. It works great this way! Works well: This product very much is a universal product and it does work with all Keurig models I might add.

I wish this was all metal. Just because i'd like to avoid plastics, BUT... overall, this works REALLY well. I use it to make Yerba Mate one cup at a time. It does a GREAT job. I always makes sure it's dumped/rinsed every time i use it, and it stays free-flowing. Only took about 3 uses to develop a ritual for efficient use. Well designed. Functions very well. A couple other reviews seemed to complain about the lid not fitting on well, or to be careful. I finde if you just make sure you push the cap on snugly until you FEEL it seat 100% of the way, and THEN twist the cap to lock it, you'll have great luck. I think maybe people were expecting the twisting of the cap to pull the strainer basket into place. But that's not how the design works. Always make sure to push the strainer basket ALL the way into the cap -- which you can SEE and FEEL - and THEN twist the cap on to the lock position. Works perfect every time. Seals fine. Enjoy! This is great value for the money. I haven't tried it with coffee grounds yet, but i can already tell it's going to work well.

This Reusable Keurig Coffee Pod Filter cup for my "Mini Plus Series" is the answer to all things perfect and pure tasting coffee❗I had no problems whatsoever, it's an easy process to insert in unit. Please follow instructions or i'll just advise here and now: First remove the original black cup inside Mini Plus (push up from under top base where coffee flows & lightly turn top of cup from inside with your other hand - no pressure) after (remove or cut tape seal holding the grey adapter to the new plastic black base cup, push down to remove-no force needed). 2nd: Remove grey lid/top with red four prong seal still attached. 3rd: Put your favorite coffee in grey plastic/mesh filter basket after 1st lightly washing/rinsing it (do not fill over line under the word MAX inside cup!) 4th: Place inside hole in unit, Lining up that small white arrow on the top grey lid to the backside of up your machine, the Keurig name & 2 lock symbols in white lettering are facing you and the front of your Keurig. The larger white circle on the filters' top (with red adaptor still attached, sealing 4 holes not needed on the Mini Plus) grey lid is facing the left side. There's no need to force the filter's entire basket in the hole. You will simply feel it a little snug as you lightly twist in place. The main thing is to be able to push close the Mini Plus's machine's top silver base over your filter cup & lights are then activated just like any other Kcup. If you desire stronger coffee, just push the "Strong" black button on top of the Mini Plus before pushing large circular silver K tab on top of Mini Plus machine when making your coffee. The coffee should pour out slowly, and cleanly (No leaks/drips/mess) from the small hole in the filter cup after water is warmed up. There is no reason to keep pressing silver tab over & over. The machine performs like a human; it knows when to start and when to stop depending on how much water you pour in container (6, 8, 10, or 12 oz<don't go over 12oz's to avoid leaks!)I'm not kidding, my coffee taste fantastic, better than my glass French press, Pour Over and is equal to the amazing taste of my Coletti Coffee Percolator that is heated by camp fire or on the stove range. This filter is even better because it's so easy to clean (I suggest cleaning after each cup of coffee is made after enjoying your delicious coffee of course) I only use water from my Brita Pitcher. I have to add, one of the best tasting coffees IMO is "Jacob's Kronung" also purchased from Amazon. And, no I didn't get any offers for this review. I am a honest, very happy buyer of great products that truly deserve their👍🏼😍
