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.
these are great but, size are way off. my wrist is 6” and since these where on sale, i bought the XS and the SM incase XS was too tight..turned out i had to take 3 links off of the XS to make it fit nicely, 1 more off would of been best for exercising since it tends to move some then but, that was uncomfortable so i just put a soft pad between band and my wrist when i exercise to make this tighter.. overall i do love this band (well after i got use to it about 2 days later), i have arthritis in my hands and this band makes it painless to remove on and off when i need to wash dishes/face/hands.. i would buy it again even though sizes our off and it really was a pain to remove links & put band back together (which btw ends up leaving a slight gap in that area)..
the bad thing about this band is that flex band part sticks out where it connects to its solid pieces, why they didn’t infuse the solid end pieces to flex band so it looks like one smooth piece/band is beyond me. where it sticks out, the edges are a little sharp.
still for $30 sale price, i’m happy with band in the end, much more comfortable then even my leather band was and it leaves little marks on my wrist.
