    The goods arrived promptly and packaging is excellent - inner foam packaging holds in place in plastic box, plastic box is in a cardboard box and the cardboard box is wrapped in bubble wrap. supplied pdf is generic and not specific to the part. plugged in usb to check and display comes to life. lack of instructions for 3 buttons make checking fully difficult. time for some searching for documentation. if supplying with a preloaded sketch at least give some idea what it's meant to do

    My esp32-s3-rlcd-4.2 works normally from usb but will not power on from the fully charged supplied battery. it only produces a red light. this happened with the original factory firmware when new and still happens with an installed radar module disconnected. connecting usb first and then removing it does not resolve the issue. please advise on a warranty replacement. thanks.

    The product is excellent and the packaging is perfect, so no damage could have occurred. Unfortunately, the support leaves something to be desired. I have not received any response to my questions. - That's why there is a point deduction!
