I had two terrible experiences with summer and will never buy their products again. First, they shipped me a thermometer that didn't work. I took the time to replace the battery and it will didn't work. I paid $9 for the themometer, called summer, and they wanted to wait until they received the first thermometer to replace it. They said they would pay for shipping but couldn't successfully send me a pre-paid envelope through email. Apparently they just didn't take the time to do it. I finally just bought another one, because it was only $9. Went to use it for the first time and...the battery had leaked all over the unit. This company is useless.

I tried other thermometers and it took to long for the reading. Sometimes I would just give up. The Summer Infant Three is really good and quick. My favorite feature is the underarm thermometer. My daughter doesn't mind it and she stay still. My only complain is that is too big to travel.

I give this product 2 stars for the variety of thermometers within one product, but the temperature always seems to be very low. I will need to purchase another thermometer, which is a disappointment.

I received two other thermometers as gifts but this was the closest to what they use at the doctor's office so I immediately liked that. Plus, it has all the attachments right in the back which means I can't lose them and I probably would have without the storage! So far, I only use the rectal attachment because my children are both under the age of two but I have had extremely accurate readings. I use this a lot, have had it a year and a half and have never had to replace the batteries. This is what I give to my friends who are expecting babies. I love this thermometer.

This thermometer is great! I love the three ends to it! You don't have to worry about cross contamination between the rectal use for my newborn now and underarm or oral use later. I've checked it against "regular" digital thermometers and taken it on the same day as a doctor's visit and I've found it to be very accurate. I also like the storage compartment on the back side of the unit because I would certainly lose the attachments!

My instance of this thermometer always reads low and varies between 1-2 degrees in consecutive readings. I just don't trust it at all.
