Munchkin makes high quality products from Infant Utensils, Dishes, to Small Toys. These Ducks are well made and have a built in Thermometer. They are fun for kids to use in the Pool or Bath Tub. In a world of Cheap / Made In China Junk ------ Munchkin Products are very high quality. Would Highly Recommend. . . .Purchased this rubber ducky for my son. It has been used twice a day for about a year and it has no paint chips, or mold. My son bites it throws it and it still looks like the day we received it. I will definitely recommend.Large rubber duck … great quality, packaged for gift giving !!!I bought this to put on a shelf and it does that very well. It does not levitate, wobble, or magically disappear. I've heard people say that it occasionally mocks them and sometimes has a menacing glare but for the most part it seems somewhat safe to have on a shelf - until it isn't.Granddaughter loves it, one of the first bath toys she grabsWhenever one of my friends is expecting a new baby, grand baby or great grand baby, I always get the first gift - the rubber ducky. They know it’s coming.I love to see it change colorsLikeAwwwwww I honestly just got this because it is (at the time) the most reasonably priced bath duck I can find. ***Note** duck looks as on sellers photo. Beak is rounded not shaped as seen on some older reviews***Its super sturdy, floats well and I didn't want it to squeak as those are harder to clean. My baby is still small And i just wanted something colourful in the bath as I love taking her baby bath photos and this rests perfectly on her to get pictures without making her feel completely exposed.As for the temperature system, it's quite sensitive and my baby is now used go water on the warmer side. This is probably not the best method to check water temp. It works by changing the colour of the loveheart from bkue to white. This changed to white frkm both ambient running water and boiled hot water from a kettle (I tested)It just takes longer to revert back to blue if its too hot so I think you're better off doing the elbow dip to be sure. But after some time you'll begin to get an idea of what your baby likes. My baby loves a bath but she'll usually cry a little the first few seconds. It takes a few seconds or minutes for her to realise she is safe and just bath time.So as i said not the best way to check the temp -use a thermometer for that if you want absolute accuracy but it makes an awesome first bath duck to have. I really like it. It's makes a great prop to sing duck songs with. Waddle waddle..My daughter for some strange reason is mad about ducks and even her first word was duck not mummy or daddy so she now has quite a big collection of bath time ducks to play with but I wanted another to add to her collection and saw this one with the temperature indicator not really something I was looking for as I find the back of my hand or an elbow more than sufficient but as it looked nice and of good quality with a reasonable price so I went for it.It is very good quality and no leaks, I did test the duck in some hot water and it worked I just feel it doesn’t really give a good enough indication of temperature and in my opinion not really accurate enough to rely on.What I liked************- Very good quality- Good price- My daughter loves itWhat I Didn’t Like*****************- In my opinion not accurate enough to rely onSummary**********My daughter loves this and I didn’t really get it for the heat testing feature that was just an added extra that in my opinion fails but that said it’s no more expensive than other ducks I looked at and it is indeed very good quality, my daughter would not let it go now and it’s the first duck she looks for at bath time so for that reason I am not being too harsh and giving it 4 stars.Bought this for baby due in January as I don't trust my own elbows (having had scorching hot baths myself for years, nothing really feels too hot to my elbow). Decided to try it out when getting a bath myself (for the same reason, baths aren't meant to be above body temperature when pregnant). I found the indicator on the bottom didn't even appear the same as the one in the picture, there is heart shape in white with hot (which remains blue) inside of it. As you can see from the pictures, there's a decent amount of "whiteness" to both of them, one having been ran under cold water and one in a hot bath. The indicator seems to become a brighter white as heat increased but there's no difinitive change point (at around 37°C) so not really any use as you would initially need to determine how white it is at 37 to make accurate use of it. It would have only received 1 star however on reading other people's reviews it has dawned on me that the lack of hole in it mean no mould and that it will be long lasting, so I shall keep hold of it purely as a toy. Was it not for the reviews I would have been giving it to the dog as a toy!It does respond to hot water but you have to turn it over to see that. It also takes a while to respond. It's a nice duck but I couldn't trust it with the babies bath temperature as you can't tell 'how hot' something is - just hot or not.In the end it just became a duck. The base quicly attracted mould around the sensor so it was eventually binned.Its a good little bath toy, but as a temprature gage I personally didn't find it that helpful as it felt more cold then actually warm to me. When used alone so I got a digital bath gage to compare it to which is obvious that the digatal would be better. But that being said I had the bath at 37°c and the duck only slightly went a little faded not the strong white so its just a little off, other then that for its price its pretty good and cute. The Rubber duck is also a nice size and quite sturdy.
