I can't believe the bad reviews. Do people know that this costs fifteen bucks? FIFTEEN BUCKS !!! I mean seriously, what do people expect for 15 bucks? First our opinion (my wife and mine) about this product: We bought this to heat up the milk in our First Years bottles: (The First Years Soothie BPA Free Starter Set ). Up to now we've only used the small 4 oz bottles, our son is now 5 months old. We think it's great, just measure and add the water, turn on and... done. Fast, easy, simple. The milk (we only use formula, no more breast milk) is 95% of the times just right and ready for our baby. Now, what is our process? Because different people have different situations. We bought a thermos (Thermos Nissan 2456P 18-Ounce Stainless-Steel Hydration Bottle ) so we boil the water and put it there. When it's eating time we make the bottle with the hot water from the thermos. If the water is no longer hot enough then we use the bottle warmer. So we don't heat up from the fridge or freezer. If you need to heat up from a really cold fridge or from the freezer then BUY SOMETHING ELSE, not a fifteen dollar product that won't suit you. Second our opinion about some of the negative comments, written by Seth Meyers from SNL (not really): -Requires constant watching: Really? A machine that turns a bit of water into hot vapor requires constant watching? What are you watching? The vapor? It just goes up. No seriously if you take the bottle in and out that will do nothing, maybe screw up the process of correctly heating up the milk. STEAM HEAT MAKES NO HOT SPOTS. You don't have to constantly watch it, it just takes a few tries to get the right measure of water and then you're good. Still shake the bottle after you take it out I mean use common sense. -The bottom gets rusty: Really? Things get dirty when they're used? Really? Well clean it up with a wipe or a bit of soap and water or something my wife says it's very easy. -Doesn't heat the milk enough. Really? It must be very refrigerated because it works fine for me. Seriously, if the milk is too cold to begin with then don't get the cheap fifteen dollar warmer use common sense. Description says bottle warmer not heater, not defroster. -Measure device is hard to read: Really? I mean really really? Are you like serious here? Turn the light on, put your glasses on I mean what are you doing that you can't read this? Someone said it was hard to read at night.. really? IT's NIGHT!!! IT'S DARK !!! What wrong with you ?!?!? Do you think the people that designed this thought maybe someone will use it in their night stand at night in the dark ??? It's a kitchen device !!! Does your kitchen have a light? Or are you using this to turn your bedroom into a steam room?? Gosh get over yourselves, use the thing in a well lit area, how tough is that? Now personally our son now sleeps all night so we don't make bottles at night but when we did we had the hot water from the thermos so no need for heating up. Just had to heat up the water in the evening (after the water was in the thermos all day) or in the morning (after the water was in the thermos all night) so again problem solved. -It only has measures for 4oz and 9oz, mine are different, it takes trial and error: Really? The fifteen dollar device does not magically calculate your bottles size, shape, how much milk there is and its initial temperature and the final temperature you want? OMG GEEEEEEETTTTTTTT OVEERRR YOURRRSELVESSSS Seriously I can't believe these people !! It costs fifteen bucks!!! What do you expect it to do???? Does common sense evade the people that buy this product? Yes it takes a bit of trial and error and then you'll be fine. I don't see what the deal is, I use measure 4 for half a bottle or emptier and 6 for a full bottle. Done. You could also buy the first years bottles, they're only 17 bucks, you get a lot of them, they're great and they have the awesome soothie shape and pacifier included. -The bottle is hot at the end and hard to get out: Really? The bottle is hot when the heating process is over? I wonder how that happened!! No seriously, if you put a small bottle without the cap on then it will be hard to get out. So... put the cap on... problem solved. Now you might have a defective product, it happens so return it and try again. Now my personal opinion, the baby can drink the bottle sometimes a bit hotter, sometimes a bit colder (I'm not saying really hot or really cold, just shades of "warm"), it doesn't always have to be the exact same temperature. Baby won't die if the milk is not always the exact same temperature. So you get what you pay for, don't expect this to be a magical device, notice the price. Want something better? Then don't be cheap and buy something more expensive. Don't blame the device on unrealistic expectations.
