Nice product. 
2007-05-05
Well designed, works well on my 4-year old daughter. Very quick & accurate; good feedback (via blinking LED) on whether you have it positioned correctly or not. Some reviewers have complained about varying temperatures when repeating the same measurement, but in my experience the repeatability is very good; less than a degree of variance. That is not a problem at all.
Takes AA batteries, another point in its favor.

It cost a little more, but it's worth it. It keeps the last 5 temperatures so you can compare.
Beats Axial and Rectal Temps for SURE! 
2007-01-25
I have a preemie who's temperature needs to be monitored pretty much constantly. At every diaper change we were taking axial temps with one of those standard digital thermometers. TORTURE! Took forever and baby screamed her head off the whole time. Then my sister got this thermometer for us and it is fabulous.
What we like:
1. When baby is screaming, the light blinks and then goes solid when temp is done, great when you can't hear the beep.
2. It truly does take a second unless baby is thrashing about.
3. Produces a long beep when you are taking your own temperature, no guesswork about when it's finished which is an improvement over earlier models.
What we don't like:
1. Preemies have TINY ear holes. So we have had to wait till our baby's ear was big enough to be able to use this thing.
2. The lens covers are a pain to switch out and keep on hand, it would be nice if there were a way to just sanitize the lens after each use.
3. We see a discrepancy of almost one degree between the left and right ear which makes us question the accuracy somewhat. The enclosed brochure explains various causes of this, but that doesn't help when trying to determine what exactly your baby's temperature is.
We have done both the axial and ear temp and found that the right ear on our baby corresponds with the digital thermometer's reading on her armpit. However, the enclosed chart shows the variances between oral, rectal, axial, and ear temperatures which make it somewhat confusing. So we alternate between the digital and the ear thermometer just to be sure.
I personally WOULD recommend this thermometer for older babies and kids, just be sure that you test it out when kids are healthy to figure out your baseline and what is normal. It takes some investigation to develop your method based on what your needs are, but it is a nice, quick to use product and my family LOVES using it for adult temperature readings. We think we will be happier with it when baby is bigger and we are using it for sick readings only.
Braun Thermoscan Ear Thermometer 2007-01-17
This product is fantastic. Instead of my 4 year old grandson screaming about taking his temperature he now likes to have it taken everyday.
Good but no light 2006-09-23
I use this thermometer with my child since he was born. Everything is ok, besides the .5 degree variant as mentioned by another reviewer and also my main complaint would be that it does not have a lighted LCD display. If you have to take the temperature while the child is sleeping the LCD display is too dark to read, you need to see it with a flashlight or something.
Fast Easy and Dependable Worth the Money 2008-03-22
I have used a few other products and they were junk but the Braun IRT4520 gets the job done. Light weight and easy to use and durable. I like the battery option using two AA's than others who have the small flat disk types. When it comes to my kids health I want to get the information quickly and comfortable as I can. I found that this thermoscan worked so well I bought two of them one for me and one as a gift.
Good product, but needs some improvements 
2008-02-09
Sturdy and easy to use. My 2-year-old kid loves having her temp taken with this thing. In fact she can do it herself.
However, if you take two readings from the same ear in quick succession, the readings can vary as much as 1 degree. That makes me wonder how accurate and consistent this thing is.
Separately, the display is not back-lit, and this is an inconvenience when taking temperatures in the dark.
Happy Mom 2008-01-16
I almost didn't buy an ear thermometer because my Pediatrician will only accept an rectal temp but my kids are too squirmy for that - even when they are sick. However, every time I have taken a rectal temp the temperature has matched the ear temp exactly. In the middle of the night, when my daughter is crying so hard that she can't talk - it is a life saver. I know within 3 seconds if I am dealing with a suprise fever or a just a bad dream.
Easy to Use & Effective 2007-11-29
We replaced an earlier model of the Thermoscan with the 4520. It seems to be great quality, painless, quick, easy to use and effective. Highly recommended.
Never worked right 
2007-05-25
We received this item as a gift and it has never worked correctly. From the start it kept saying "low battery". The batteries are very diffictult to change out and the ear piece never fit in my preemie daughter's ear. We use a different ear thermometer that is so easy my daughter (now two) can even work herself! I would not recommend this product to anyone!! It has been a piece of junk from the start and no end of frustration and money with the lithium batteries!!
