General information about our shipping
I've only been using this for a week but so far for the price I don't think you will get more value for your dollar. It has almost everything you need to train at a low cost. Obviously it's not a power meter but you wouldn't be looking at this if you could afford one. It calculates power in a fashion but I wouldn't depend on those numbers. It has heart rate, speed & cadence which is all you really need up until you cross your lactate threshold heart rate so once you start anaerobic training you'll just have to use your perceived effort. Another plus is that it comes with the docking station & software so you can upload your workouts & analyze them. My only minor complaint so far would be that it has a couple second lag before it starts reading cadence & speed however it could be because it's wireless but it's not enough to be a problem, just a little annoyance. Overall, I think it's a great product for someone on a budget.
Top computer at a top price, you can log your rides and compare the data on your PC or Mac. Comes with all the sensors required to monitor every aspect of your ride, there are only two downsides to this computer that bother me which are, the speed sensor is on the front wheel which means its no good for using on the turbo trainer and the second is that if you don't put the computer in to "log" mode it will not record any useful data during the ride, it still records the distance and elevation but nothing that can be used for training.
