I generally don’t leave reviews but if you love Sparkling Water/Beverages. You need this - it will be healthier, it will save you time going to the store and save you money.The Monten takes absolutely no time to set up, no outlet required, you can purchase the bubbles right here on amazon for $30 or less (I expect the carbonation bottles lasts a long time, as it’s months in and we’re still on our first), you can control exactly how carbonated your beverage is and it takes 5 seconds or less to create a fresh bottle of sparkling water, sparkling lemonade, sparkling tea or the like.There are so many fun recipes with crushed berries, lemon, lime, mint, zest etc on YouTube if you like additional flavour - and they are all so easy, and the best part - FRESH! No artificial ingredients. We personally think what we can make with the Monten tastes better than even the highest end brands of sparkling/mineral water we were buying at the store.Bonus - the customer support is phenomenal if you email/call them directly. I don’t know how you could leave a bad review for this product or this company, unless something went wrong like shipping or the like. It’s great!I had another machine like this, that was never used - this is so simple, it’s used everyday, multiple times a day. We love them so much, now we’re giving them as gifts.
