Okay, this bottle warmer! The steam system is much better than when it dips into the water. By cons, it's quickly calcify, so, you have to go a little vinegar regularly. The only flaw, and it is a defect that annoys me royally, this is the kind of measuring container. The graduations will see little, fade quickly (2 months of use and it's starting to fade), but the worst thing is that the plastic is a dark color (brown), and suddenly we do not see the water level when filling. And that's enough to fill hassle because it takes very little water, so was quick to put too much, and clear, to spend more time than it takes to prepare the pod. my husband also rattle every time he uses it. It's a shame because otherwise it's really good.
