I bought the Sparkel for my husband after he tried a sodastream several years ago and was disappointed. The Sparkel has much, much more consistency with the carbonation level across multiple uses. We also like that it is more environmentally-friendly with recyclable packets. The only improvement I can think of is to release a bulk option for the carbonation packets so single use packets wouldn’t be necessary, but it’s okay since the plastic used is recyclable. Overall, quality is great and ease of use is high!! We recommend this over the soda stream.

I've been wanting to try a carbonator for a couple of years now. I was not thrilled w/ having to use and find refills for CO2 tanks -- particularly as COVID restrictions rolled out. I tried to review every site I could find online regarding brands and customer satisfaction. Points that led me to give Spärkel a try: a broader range of beverages that I could create; the easy-to-use carbonator packets; the company's environmental commitment: Spärkel has partnered with Cleanhub to create a Carbonator Offset Program. For every Spärkel Carbonator sold, they collect the same amount of ocean-bound plastic from the environment. It is not a cheap system to purchase but with their holiday special and free shipping, I couldn't resist! So far, I'm very happy and having fun creating new carbonated drinks -- for example, wine spritzers are a delicious way to boost average tasting wine especially during this holiday season! Cheers!

They are a little pricey. But, the convenience of the packaging and the certainty of the measurements make it worth it to me. I especially like how they are tied together in pairs, making it fast and easy. My only complaint is that it is virtually impossible to rip them open. You must use scissors.

So far, I have enjoyed the various levels of carbonation. Its easy to use and economic as well. I am saving overall more than 20 cents per serving, may be a bit more. In terms of waste, the plastic packets and cardboard box they arrive in are the chief waste items. I would not be able to speak to the comparative impact of cans or bottles as all of our recycling here is voluntary, but it appears to reduce overall waste volume.

I sent this to my daughter for Christmas and she has not opened it yet.
She was pleased to receive this as a gift.
