Loading Ratings & Reviews...

New Balance LifeTRNr Bluetooth Fitness Monitor is rated 2.75 out of 5 by 4.
Rated 2 out of 5 by from False Advertising First I would like to say the watch itself is not bad at all regarding it's size. It's compact and the fact that you do not need a chest strap is great. Functions are basic. Easy to set up. Heart rate has a hard time reading a sweaty wrist so bring a towel on your run so you can dry your wrist before taking a heart measurement. Other wise it works. If you sit down at a desk, it will read all your hand movements as steps so take the steps reading with a grain of salt. It will be higher than usual. Not a big deal but not the most accurate. In low light situations like night runs, the screen is almost impossible to read even with the back light. The APP is not free. It does not work with my MAC BOOK as it claims to. The only difference between this model and the other is the BT capability. So far I have not been able to sync any of my data. Mostly I use it for the heart rate just because its easy. The other information is useful but not as accurate as I would like. I have been using the NIKE Running app which is free and uses my Phones GPS and thats been great. Getting a quick HR helps me know how hard I'm pushing myself. If I can't get the app soon. I will return it and get non BT model, which they sell at Costco for a lot less. Love REI but my pocket come first. Overall, the watch is great but the fact that it does not sync and that the app is not free turns me off. Heart rate is great and accurate. All other reading are based off of your movement which is skewed by counting extra hand movement. If you're latin or Italian or talk with your hands, You will get a lot more steps than usual. If it did everything it says I would give it 4stars. I would probably recommend the lower model to a friend but I'm not sure about this one only because i don't have a 5S, and I'm not going out and getting one anytime soon. I have a Galaxy note 2 and it is not compatible. Maybe i'll wait for the app to hit the Android platform. But not for long.

Rated 3 out of 5 by from Almost there The instructions and all of the advertisments talk about a "new balance fitness app" thank syncs with this device. I can not find such an app in the app store however, nor can I find anything on the internet talking about where I might be able to find it. I've looked at the new balance website and the manufacturors webstie to no avail. I've emailed and we'll see. The product seems to function otherwise great, I just need that app!

Rated 1 out of 5 by from Wanted to love this watch.... I really wanted to love this watch! I was looking for a heart rate monitor without the chest strap and thought this watch would be a good fit. In order to get a heart rate I had to stop the exercise I was doing to get my finger on the screen just right and then wait a bit for it to calculate, not great for interval training or running. Once it did calculate the screen was almost impossible to see, especially outside. Wearing sunglasses made it even worse. The watch is very bulky and difficult to get on. I am not sure how accurate the data was for calories burned and distance traveled, none of the information given even came close to data calculated on gym machines. I returned this watch to REI.
