Works as expected though it won't pair with my iphone and therefore I can't link it to Strava. My main frustration is that I only bought it because my Polar monitor won't pair with my Cateye Padrone Digital computer. It is a Cateye fault not Polar as the Polar monitor pairs with other devices just fine.
Very functional Cateye headband combined with the Cateye Padrone Digital. Great price and fast shipping! Recommended *****
Go for Cateye and save your moolah! - Thanks Cycling Boutique for the guidance.
recive faster and oportunity is good
I have only used once but it was great to have the feedback while training on the bike. Easy to sync with the cycle computer and i phone. Can't feel it while riding. Only drawback is eventually the strap will need replacing if you train hard enough to make it wet. I'm really glad I got thiis.
Comfortable feel while riding, although I have only used it a few times. But it was great to have the feedback while training on the bike.Easy to sync with the cycle computer...once I had found out that the battery had to be replaced.
Synchronises easily with cat eye smart range. Best of all, as it is Bluetooth it is a doddle to hook up direct to strava on an iPhone so I use it on the mtb where I don't use a computer.
