TZMRIT AULA S99 99-Key Wireless Membrane Keyboard

TZMRIT AULA S99 is a wireless membrane keyboard with a number pad, RGB backlighting and a claimed three-mode connection. It may suit desk setups that need numeric input and multiple connection options, but the listing conflicts on the connection details and explicitly says the membrane model is not hot-swappable.

What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: connectivity fields say Bluetooth, USB-A, USB-C and Wi-Fi, while feature text specifies Bluetooth 5.0, 2.4GHz wireless and USB-C. Hot-swapping is claimed in one field but explicitly denied in feature text. The description also varies between 99 keys and a 96% layout, and the advertised keyboard is not corroborated by the explicit box list. Check the selected listing for the exact configuration and kit.

Frequently asked questions

Is the AULA S99 mechanical?

No. The listing describes it as a membrane keyboard.

Does it support hot-swapping?

The listing conflicts on this point. A feature field claims hot-swapping, but the product description says the membrane model does not support it. Treat hot-swapping as unconfirmed.

What connection options does it have?

The details list Bluetooth, USB-A, USB-C and Wi-Fi, while feature text instead specifies Bluetooth 5.0, 2.4GHz wireless and USB-C wired modes. Confirm the modes for the selected listing.

What is listed in the box?

The explicit contents list names a USB cable and user manual. The keyboard itself is advertised but not corroborated by that contents list, so check the selected listing.
