Query: Product works as expected

Got this battery which is an exact replacement for the dead one I took out of my watch. The product definitely works as expected. The only negative feedback I have is for the seller. The product arrived several days after the latest estimated delivery date. This technically was outside of the sellers control, but they failed to proactively inform me that my delivery would be delayed, even though they knew it was going to be delayed.
