Guests appreciate the great taste and customization options of the drink mixes, which can be easily adjusted to personal preferences. Many enjoy the convenience of using the product without needing to visit a store, highlighting the ease of ordering and returning CO2 tanks. However, the absence of a measuring cap in the new bottles has caused some frustration, as it complicates the measuring process for syrup, leading to mixed feelings about the new design.

Hate the new bottles
The new bottles do not include a measuring cup in the cap. This is very inconvenient--apparently we are expected to buy all new plastic soda bottles with marks on them for measuing the proper amount of syrup. Disappointing.

Just as good as the real thing
Easy to make, tastes just as good as the actual cans/bottles, and is cheaper!

While I received my CO2
While I received my CO2 cartridges, unfortunately only one bottle of the drink mix was received- although I ordered four and I'm sure my entire payment was taken.

Refreshing
Pepsi is one of my favorite drinks for its good flavor and consistency; I usually drink it frequently, especially in snacks. Now that the heat has arrived, it is, without a doubt, my favorite.

Perfect for any meal.
The only thing I would drink with my lunch, the flavor is perfect not too sweet, and not to blend no aftertaste, no sugary aftertaste. I enjoy it best with couple of ice. Perfect for every meal.

Used without the soda stream, just mixed into regular water. Doesn't have quite the same flavor as pre-mixed, but it's close enough, and you can tweak the ratio to taste.

Delicious!
Exactly like the real thing! (Honestly a bit better because you can customize how much flavor you use)

Happy
always fun to talk to support and I usually call, but I know that ordering is simple and so much more convenient than finding a store that has the sodastream and even knows how to do an exchange of the full and empty tanks. This is so easy and shipping the tanks back is so much better than lugging them into the store to exchange. I love sodastream. Fine product and great service/support if you need it.

Taste is like Diet Pepsi
The generic Diet Coke tastes bad, IMHO. This I like. The container is great

New flavor bottles are poorly designed!
I agree with another customer. It's best to save at least one of the original bottle's measuring cap. Without the measuring cap there is no way too know how much to add to bottle of sparkling water. I'm saving several original caps clean in the dishwasher.

Disappointed
I use pumps that are made for the original bottles. I love them a lot! Really dislike I can't use them anymore.

New Bottle Design
Well the new syrup bottles look great and I’m sure they are significantly cheaper to produce. Problem is having to measure the syrup now. I don’t need new bottles.

Poor flavor bottle design
What's with the new cap on the diet pepsi. Fortunately I kept a cap from the old style bottle for measuring. Very poor design from a customer perspective.

New bottle design problem.
There is a problem with these newly designed containers. They don't have a measuring cap like before. Now you have to use a measuring spoon.
