I bought a Coin on kickstarter and they got blindsided by the EMV transition and rather than shipping me a piece of junk on time, they shipped something that addressed the major problems later.
A lot of people complained but I felt they acted with the highest integrity and if they do another startup or come out with another product I will want to do business with them.
I have bought products and been contacted sellers who had sincere desire to have me be happy with the product and encourage me to return the product and get a replacement if I find any defect at all. You can find these people in Peoria and you can find these people in Shenzen.
I bought products from Fitbit which all had some problems and found that the people there would try pretty hard to not give you an RMA.
Maybe other people have different experiences and I don't know much about their situation, but I did buy a Withings scale and it worked perfectly from day one and if I do get another fitness tracker it is going to be a Microsoft Band or one of the seemingly hundreds of other products in what is a crowded marketplace.
