This is an amazing product! At this price point, I didn’t expect it to perform as well as it did. I have used it to open 4 different bottles of wine, and it worked really well. I docked one star because there is no outward charge status indicator (e.g. an LED to show charging, charged, or needs charging). A nit pick perhaps, but I find it an inconvenience.
