I purchased a heart rate monitor from 1 day sale and when I received it i thought the transmitter (the part that gets sweaty) looked used, so I contacted them and they told me to send then photos, which I did. About 2 hrs later I received an email saying that they have contacted their supplier and the supplier are going to send me a new transmitter.
I thought it was pretty well resolved. Now I just gotta wait to receive my new transmitter.
Update: They just handballed it to the supplier who said that what the wear marks on the transmitter is normal. They would replace it for me if I sent it back to them…at my cost
Polar FT-60? - I bought the same one.. it's good.
