Customer Ratings & Reviews

Even when you take into account the cost of the soda maker, gas, and this concentrate you break even vs. buying Red Bull or other canned energy drinks very quickly. Once you get used to it the taste is great, although I prefer the black bottle better because this one has a slightly over-sweet aftertaste. This version is zero calories, though, so it's a tradeoff. It's so convenient not having to go to the store to get your work/gaming/workout fuel!

I love my soda stream and have found this flavor to be my favorite. I enjoy mixing it with orange or grapefruit to make a flavored energy drink. I save a lot of money every month by not buying energy drinks! Great flavor!

I like this flavor - like Redbull. SodaStream is changing it's product line and packaging so this normally $10 bottles were going for $3.99. Grabbed up as many as I could and no longer see DIET Energy on the shelves anywhere. The new version will bo out at some point.

Great taste with a diet product I really love taking it to work for the shifts I know are gonna be long, tastes like red bull and is much cheaper

Love the flavor, great taste, and compared to Monster and Rockstar brand cans you buy individually at the store, this is great price too.

I love this energy drink, but this was my first time ordering through Best Buy. I figured I might as well go ahead and order 2 so that way I wouldn't have to worry about running out, but when it arrived both bottles were all dented up (which I can get past). However, they both expire in a month. So now I have to worry about trying to finish both bottles all by myself in one month. When I've ordered from other sites they've had a year before expiration. So I am not very pleased. If you order from them I would suggest only 1 bottle at a time. Will give them an extra star for fast delivery though.

Great price and great taste. Saves me money buying these syrups. Similar to red bull but much cheaper.

This stuff is as close to sugar free Red Bull as you can get. Save TONS of money and get this stuff!

There are many arguments about if the side stream system actually saves money. The argument stops here. This taste exactly like diet red bull at a fraction of the price. This one bottle will have the soda stream pay for itself.

Since this size is being discontinued I bought several flavored on sale. A fraction of original price and the new style of bottles will actually have less ounces of fluid but same price as the old style. I like that they offer the diet version of this energy drink!

If you like energy drinks and you have a Sodastream then you have to get this. I am not a coffee drinker so I drink this every morning before work and by the time I get to work I am ready to go. I would compare it to Red Bull, actually I don't know if I can tell the difference between the two of them. If you think the taste is a little strong for you then you can always mix it with another Sodastream drink, I do this a lot to. Sometimes you don't want to drink it at full strength. It is my favorite drink that Sodastream makes. Anytime I see them on sale I buy as many as I can afford.

great taste less expensive then red bull. save alot of money with soda stream.

I really enjoy my soda stream machine and my favorite mix is this diet energy formula. It says compare to Redbull on label and is less expensive than the name brand to make and tastes pretty good.

If you like Redbull and have a Sodastream machine, you really should try this (or just pour it in club soda-- same thing).

If you love energy drinks but don't like dishing out $2-$5 per can this is a great solution for you! For the cost of two canned energy drinks you can make over 20 from this bottle of syrup if you own a soda stream machine. The only drawback is it only comes in one flavor, but if you like saving money, this is a great product.

This is my husbands favorite soda stream flavor. And it was on sale cheaper than the other stores so I win!!

Close to the no sugar Red Bull taste. Out of all the SodaStream brand products, this is the one that is closest to the original it tries to copy. The diet orange is my second best with the Crystal Light Diet Energy Wild Strawberry. All the generic copies (non-Crystal Light or other brand names) have been pretty nasty and not even close to what they try to copy. This Diet Energy is solid.

The reason I use the Soda Stream so often. Has already saved enough money to pay for our Soda Stream.

Using this instead of canned energy products has been very good and in the end cost much less.

Best prices around love my soda stream and getting the items from best buy makes it affordable
