My power meter arrived CRACKED and with two dead batteries. I suspect that my cranks were returned by someone else and resold to me. Unfortunately I did not open the box to install the cranks because I wasn't ready to build the bike until after the 30-day return period. Power Meter City isn't helping me out except pushing me to the manufacturer. Unfortunately, I would recommend shopping with a larger business rather than helping out a small business. Power Meter City is not standing by the product that they sell nor did they do QC before sending the product out. At least a large business has some margin to take some hits on profit to prevent bad impressions on customers. Edit: I admit that I should’ve been responsible to inspect the product as soon as I received it and I did it. However, the reality is, I was provided a product that is defective. After spending well over $1000 on a product I would expect a some kind of gentleman’s agreement from a small business with the level of service that comes with them. I won’t be shopping here again nor will I recommend anyone else do either.
