LE sensor review for SKU IQ for TikTok Shop or POS

inventory didnt sync so i made an call two weeks out as that was the soonest available. No one showed up and to reschedule a call was another 2 weeks out... Emailed back the company twice and no response. Decided not to use their service after that experience. All i needed was to know WHY my inventory on shopify wouldnt sync to up.
