This computer does everything as advertised. I found it difficult to set up and use all its functions. The learning curve is fairly steep (I’ve been out of cycling for a while); keep the instruction book handy. I did not have a particularly difficult time setting the sensors. One thing I was disappointed in is the wireless range is very limited. If you want to put the speed sensor on the rear wheel then this unit is not for you. Also the crank arm attachment for the cadence sensor is not very good. The tape provided is not very sticky. I suggest going to your local hardware store and buying electrical tape in a color to match your bike. If I was buying again I would not buy this unit; I would probably buy a wired unit instead. One other thing is if you want cadence on the big display I don’t think it can be done. The heart rate monitor worked very well if you follow positioning instructions.
