Update after my original review
Initially, I had a very frustrating experience because my package was marked as delivered but never arrived, and communication from support was very slow. There was a lot of back-and-forth emailing and waiting throughout the process. However, to be fair, the GravaStar customer service team eventually contacted me and arranged a replacement shipment. I have now successfully received the replacement package, and everything arrived safely and in good condition. I still believe the communication and support process during lost-package situations could be improved, but I appreciate that the company ultimately took responsibility and resolved the issue.
