It's no more a con than buying a car to discover that you have to put petrol in it. The buyer should have made sure they understood the product.
While it's true that you can use the pod with any shoes the pod is designed to be stood on, so it's more accurate when placed under your foot.
No. The sales-person said it was ready for Nike+, which is only a half-truth. The customer shouldn't be expected to know everything about the product, but the sales-person should.
Elliot, if you use the Nike plus GPS app which you can get on an iPhone 4s, you don't need a sensor anyway so can wear any shoe you want. The iPhone has GPS built in so I think you only need the sensor if you are just using an iPod nano.
The sensor is still £15-£20 and can not be recharged and the battery can't be changed. Bit of a rip off.
I think that the Nike + compatible shoes have a little compartment under the insole where you put a sensor. I do not use Nike + app but do use the compartment to put the foot pod sensor for my Garmin as it fits perfectly.
My missus has bought some "Nike+ Compatible" shoes but both a fourth-generation iPod touch an iPhone 4S can not detect them.
Even though they're "Nike+ Compatible", does she still need to buy a sensor? If so, what makes the shoes "Nike+ Compatible"? Surely any shoes would be? Is it a con?
