As Expected

As a long time user of Twist-O-Flex Bands it Is a comfortable and attractive addition to my new Apple Watch. Perfect fit.


Bought watchband and it was too small asked if I could get extra links and was told of course we can we’ll send them to you
Never arrived and ignored my emails after that
Had to buy a second watchband meaning I had to pay around £200 to get what I needed
I would not recommend your after sales care as it is non existent




Twist-O-Flex Band for the 38/40mm Apple Watch


It’s exactly how I expected this band to be. Finish is perfect, feels like high quality material. The only thing I don’t like, hence the 4 stars, is the way the band fit in the watch. It feels a bit loose, like pretty much every 3rd party band i’ve bought. It stays in place, but is not tight. Would still recommend, I won’t take it off!
