What to know before buying

Listing details to confirm

Listing details are contradictory about the included supply of 4 × 6 inch thermal labels: the contents list says 15 pieces, while a feature claim says 25 sheets. The feature text also claims speeds up to 150mm/s and 72 labels per minute, while structured details label 72 pages_per_minute, so the applicable speed measure is unclear. The claimed included power cord and USB cable do not appear in the explicit contents list. Check the selected listing for the package quantity and speed details.

Customer feedback highlights ease of use, quick printing, and reduced ink and label costs. Connectivity, print quality, and label feeding are mixed, with reports of Bluetooth disconnections, problems on the first few labels, and skipped labels. Those concerns matter for shipping workflows where consistent alignment and reliable connection are important. The listing's Bluetooth app and USB options provide different connection paths, but do not establish that individual printers will avoid these reported issues.
