LifeBEAM Hat, One Size, Black/Silver

It works as promised. I had to manipulate the straps a little to fit my head ( probably just my head). Stays in place accurate reading compared to my watch and arm band.

Like the concept, love that I can pair the hat with my suunto, somewhat disappointed with the battery life. I used it for one half, hour walk, one 2:20 hour run, and then found it flat next time I went to use it. Will keep an eye on this and maybe amend my assessment based on this. Under three hours is really pretty useless for someone who likes long trail runs.

So far very happy. As accurate as the polar chest strap and far more comfortable and practical. Have not yet tested with some apps like Edomondo. Charges fine. Sometimes the on-off switch is cumbersome to find even with or maybe because of the raised power button. Great progress compared to chest straps. Would recommend.

My Lifebeam hat seems to have failed less than a year after purchasing. Having trouble finding a way to contact Lifebeam to get it fixed or replaced. Connects to my phone for only a few minutes or not at all. Basically not functional at this point. It did work well for 8 or 9 months. I am using Lifebeam's Android app.

I bought this hat because of chafing issues from using a chest strap. Unfortunately, after less than two weeks the electronic unit started going haywire. It would stop working in the middle of the a run and beep constantly and eventually lock up. I have a ticket open with Life BEAM but unfortunately they haven't resolved the issue yet. I'll update my review when I hear back from them.

These are so comfortable and convenient. Prefer black with most gear but like white on warm, sunny days. They hand-wash easily, just remove the rectangular battery pack, first. Have worn them on several high-elevation-gain hikes, runs and races and they seem to be very accurate. Also work under bike helmet so hardly ever have to wear a chest strap.

Ordered a black hat, got the white one.

When it works it does a great job, if you live in a hot humid climate you are going to be out of luck. I live in South Carolina after about an hour once the hat gets drenched in sweat the hat stops working. This is on a full charge as well. Going back to my chest strap this was a waste of $100.
