This Speidel twist-o-flex band for my Fitbit Alta HR fits great. I have gone through several bands over the last couple of years and l am lucky to get a good six months out of them. I found this Speidel Fitbit band while browsing. In the past my Fitbit didn't record all my sleep time as l toss and turn some nights, the loose plastic or leather band wouldn't keep the back of the HR against my wrist. This band keeps the HR flat all night long, but it's not too right. I measured and ordered the proper size. If l had known Speidel was still in business l woul have bought one of these bands when l purchased my Fitbit Alta HR. I am seventy years old and used Speidel watch bands on my watches years ago. Their product is still outstanding....!
I love this band and wish they made more variety, but then again my FitBit is kind of old LOL.
This band is so easy to slip on...no more fiddling with poking into a hole to make my Fitbit just the right size. The brushed silver look is perfect for professional settings up to semi-formal functions.
I had been using the plastic and leather Fitbit Alta HR watch straps since I purchased it a couple of years ago. They didn't last very long and were not tight enough on my arm to be accurate. The holes were either too loose or too tight. I saw the Spiegel Twist-o-Flex watch band advertised and I remember having one on an old watch I had many years ago. I purchased one for my Fitbit. It arrived in a short time and when I opened it I could see that it was well made just as the one I had owned before. I had looked on the website and measured my wrist to be sure before I ordered it to be sure I got the correct size. The Speidel band clipped onto my Fitbit without any problems. When I put it on my wrist, the fit was perfect, it holds my Fitbit against my wrist, but it's not too tight. I had a problem in the past were the leather or plastic band would be pushed off the surface of my wrist when I was sleeping against my arm and the sleeping and heart rate would not always show the correct readings. Since I have worn this band my readings have been constant and more accurate. I would highly recommend this watch band.
