Ok so.. Tricky to set up on the bike... the magnets, the sensors (got a cedence sensor as well) and the unit itself have to be installed to quite specific tolerances. You have NO freedom with regards to where you're installing the parts and the unit - which is something I really dislike.
When biking, the unit MUST be on the handlebars, right above the sender for the speed/distance - you cant wear it. Unimpressed.
It's handy enough as HRM, and as a watch.
I'm missing GPS functionality, or even capability to function with a GPS module.
All in all - I wish I'd gone for a boggo bicycle computer and a seperate HRM paired with a GPS.
There are competing solutions from other manufactures that I'd be looking at before buying this & I wish I had when I placed the order.
Unimpressed.
