Observation Details
The manufacturer filter (direct filter buttons in device carousel) can only be operated by horizontal scroll on desktop and by dragging movement on a mobile device. As the dragging needs a base precision to stop the movement at the right time to reach the wanted filter button, a single pointer alternative for operation / navigation must be offered.
The viewport of the example screenshot is 375×635px, simulating an Apple iPhone 11 Pro. While this is an old device and more current phones do tend to have increased viewport widths, this test would look even more drastic on the 320px viewport width, the WCAG sets for e.g. 1.4.10 Reflow.
Remediation Notes
Possible methods to remediate and to ensure access to the buttons:
Adding pagination (single pointer arrow buttons)
Reflow to multiple lines of buttons (also see 1.4.10 Reflow)
