Big Buddy 3 in 1 Plastic Bottle Cooler Cocktail Shaker and 24 oz Tumbler in 1 - World’s First Stainless Steel Cooler for 20 oz Bottles - Dual Lid Function - Non Slip Bottom (Beach Buddy)

Does not fit Australian 600ml Pepsi Max with included collar

I am not one to write reviews but I had such high hopes for this product. While not a bad product it clearly does not do as advertised. My 20oz Mt. Dew bottle did not fit and several 16.9oz bottles of soda also did not fit. The main reason for purchasing this product was to keep my 20oz and 16.9oz bottles of soda and water cold but if the bottles don't fit then it is useless. I had thought about returning, but don't want the hassle so I will use it for the few bottles that do fit for now.Buyer beware that 20oz Mt. Dew did not fit....16.9 bottles of Wild Cherry Pepsi and Orange Crush also did not fit.

This is the best! I HATE to sip on a bottle of soda and have it get warm. It’s so wasteful. I bought this with high hopes that it would hold my 16.9 oz Diet Cokes and keep them cold long enough for me to drink it though out the day (I’m a sipper). This does the trick. It exceeded my expectations and my drinks stay cold for hours. Highly recommend the 20 oz size.

For a guy who does not like water unless cold this thing is amazing. Example of how well it works. I mowed for 2 1/2 hours came back to the house and thought well going to have to get another bottle of water because this one is not going to be cold. Hell it was just as cold as it was when I put it in there 2 1/2 hours ago. My wife has been on me forever to drink more water instead of Coke Zero all day. I drank maybe 2 or 3 bottles a day. Now it's like I can't get enough. I tracked just for the heck of it and literally drinking 12 to 14 bottles a day now. It has made me feel better and I have kidney issues and has helped with it. Who knew a simple water bottle holder/cooler could change so much...lol

So I've had this for one day only, but already I'm beyond impressed. On first view I was thinking, ok, so it's a metal enclosure with a cap on it...no way this is going to help."Incorrect, young Padawan."I haven't done any testing to see if it meets what they "claim" on it keeping plastic bottled drinks cold for 12 hours, but I can say this. After 6+ hours my cold drink still stayed cold. I mean quite cold. Usually within an hour or two, I'm putting my drinks back in the refrigerator because they've already gotten warm. Haven't had to do that one since having this.Just in case there is any confusion, like I had. The pictures you see on here, showing the bottles inside of the can through a transparency, is only to give you an idea of how they fit in the Frostbuddy. You do not actually see the bottle in the can. These are all metal construction except for the plastic tumbler lid or the silicone bottle holding one.The product also comes in a nice box and isn't one of these typical off-brand items you find at Amazon where they ship you a loose piece in a plastic bag.Again, I haven't had it long yet and I might discover issues with it, but so far I'm VERY impressed. (Also the bottle rotating in the canister is such a non-issue, it is almost funny.) Yes, on a smaller bottle it will rotate if you try screwing the cap on or off, unless you gently put a finger on the part of the bottle that sticks out. That literally is all it takes to keep it in place when unscrewing the cap.Hope this helps a bit.
