>>9727201. I can't find a webpage for the manufacturer, therefore it's probably cheap Chinese junk
2. What there is about it in your link says nothing about it being Ant+ compatible, therefore I'll have to assume it's not, and works only with whatever cheap shitty Chinese sensor(s) come with it.
3. As someone else stated: No cadence display. DO NOT WANT.
4. Price is too low, therefore more suggestion of it being cheap Chinese junk
5. Unless it's USB rechargeable (doubtful) it'll eat through batteries because of the backlight
6. Who cares if it's got a thermometer built in, really?
If you didn't figure it out already I think it's a piece of crap and you'd waste your money.
If you want wireless get something that's Ant+ compatible so you're not stuck with proprietary sensors you can't replace if something goes wrong with them.
If you want backlight and whatnot it needs to be rechargeable unless you like replacing a battery all the time.
