While everyone's focused on price movement, a few other items to ponder....
1. New SodaStream commercial up on YouTube - just search for Bubble Love SodaStream and you'll see it
2. It was appearing that SodaStream's search engine trending would not match 2013. Since the Super Bowl, not only has it met, but blown away all time search volume. If you go to Google Trends, search SodaStream it will show you the global historic trend, then you can segment by country, time period, etc. The trend is your friend.
3. SodaStream consumables are rising the charts in Amazon's top 100 of kitchen & dining. Traditionally out of the top 100, bottles are now firmly at #40 and have been rising the charts steadily confirming consumable usage.
Good luck, off to make myself a liter of 1/2 Country Time Lemonade, 1/2 Crystal Light Strawberry Energy. That's right, we can customize with ours! ;-) (Open platform)
I drank 2 bottles of 2 liters carbonated drink in 1 week, and gained 10 pounds, I won't say which brand, but it's definitely not Sodastream, now I have to work my #$%$ off to lose that weight, never again I drink sugar carbonated drink. Sodastream is going to be on my kitchen counter from now on.
We have two machines, soon to go for three to include the outdoor entertainment area. Now, we realize that skews the machine sales vs the flavor and carbonator sales, but SODA can live with that.
Just be sure to keep a good amount of SODA shares put away for your future. When home carbonator sales are 25 percent of worldwide beverage, SODA can have grown thousands and thousands of time over.
