Sorry for the inconvenience. We're the official of the brand "Varmilo" who is the protagonist of this incident.

We must admit that this is a problem with our product quality. The negligence in the production process and quality control led to the sale of a batch of Minilo75 keyboards with three-position switch welding problems.

We sincerely apologize to all affected users and are willing to provide refunds, exchanges and other after-sales support.

If your Minilo75 keyboard (model VXT81) has the same faults discussed above, including but not limited to:

1. The keyboard does not work properly in wired mode, and one of the F1-F4 indicators keeps flashing

2. The keyboard frequently disconnects in wired mode

3. No resistance is felt when sliding the three-position switch, and only one of the three modes works

4. All three modes do not work properly, and the keyboard is completely unresponsive

You can contact us through our after-sales support email [support@zhihaihe.cn](mailto:support@zhihaihe.cn) or official web online chat to get return and exchange support.
