Bests & Worsts Reviews from Amazon

READ THIS if you're evaluating overall price of using this unit. What I did not read ANYWHERE was about the CO2 cartridges as well as the rebate (thank you) offered with this starter kit. Pricing replacement cartridges kinda expensive for $30 - $40! I called mfgr - very professional rep explained how it all works. You take the starter CO2 that comes in package to Walmart (or Target) customer service & they will charge you $14.99 for a full size replacement CO2 cartridge (and you give them the "starter" CO2 cartridge). Apprehensive at first, but customer svc dept Walmart actually had a sign posted and plenty of cartridges in stock. I'm so glad for initial rebate & phone call because I was going to order couple CO2 cartridges, but I decided to just order 1 so when 1 runs out I have a spare until I can get to Walmart to swap again for $14.99. I was relieved that the cartridges are only $14.99 during trade-in process. I can actually do it myself and it's EASY. NO twisting, no individual cartridges, not too heavy or bulky. We've tried a couple different kinds of "bubble" water makers. Just don't over fill these bottles, really, or there will be a little water on the counter. Otherwise there is no dripping or any spillage whatsoever. Owned it about a month now & I use it daily. I ordered the 2 pack Sodastream Twin pack water bottles so I could have 3 bottles total so the water could get & stay cold in fridg. Thanks America's Test Kitchen as well as other reviewers for detail about this.
