Bests & Worsts Reviews from Amazon

I bought these thinking I would save money with the soda stream brand but i ended up spending much more. SodaStreams new exchange program is only $19 per cartridge compared to this which would be $38. I got my SodaSense cylinders and neither worked. After calling their support (which were super friendly!) they said they fill theirs up so much that the pin on top is too tight. So I had to spend 5 minutes slowly releasing gas and then checking again. Finally once I got it working I made myself a drink. The SodaSense doesnt seem to function in the same was as the SodaStream cartridge. There's no sound of the gas release which is what i used to gauge how much I needed. I definitely wont be buying these again. It seemed crazy that i had to expel so much gas before getting it to work, not work $80 Update: The second cartridge that i used did not allow me to save half the tank but rather it didnt work until EVERYTHING was released from the can. So this means that I paid $80 for half of one can (like 5 drinks). Complete rip off
