Hey everyone,

I’m Vicky from the ProtoArc team. We’re back here because this community gave us some of the most helpful feedback on our EM11 NL last year.

Since then, we’ve heard a lot from EM11 NL users about what they wanted improved:

• Customizable buttons
• More room for larger hands
• Moving the channel switch button to the top
• Adding horizontal scrolling

So we built the EM11 Pro around those points.

Now we’d like to invite a few more testers here to try it out and tell us what works, what doesn’t, and what feels awkward in daily use.

If you’re interested, please do two quick things:

Step 1: Leave a comment answering:
Based on your experience, what’s one thing you think most vertical mice still get wrong?

Step 2: Fill out the application form:
https://form.jotform.com/261512625410042

We’ll use both the comments and the form to help choose testers, so honest thoughts are appreciated.

A few details:

1. The sample is free, shipping included, and you don’t need to return it.
2. We can currently ship to: US / CA / EU / UK
3. We may not be able to include everyone, depending on responses and shipping availability.

Thanks again for reading. Even if you’re not interested in testing, feel free to share what you’d want improved in a vertical mouse. We’re here to listen.

Hey everyone,

I’m Vicky from ProtoArc. I’m really excited to share that EM11 Pro is now available for pre-order.

This product means a lot to us because it didn’t start from a feature list. It started from user feedback.

• Customizable buttons
• More room for larger hands
• Moving the channel switch button to the top
• Adding horizontal scrolling

So we built EM11 Pro around those points.

We’re also honored that EM11 Pro received a 2026 iF Design Award, but what matters most to us is whether it actually feels better in daily use.

Before launch, we invited some EM11 NL users to try early samples. Their feedback helped us confirm what felt right, and also reminded us what still needs work.

Seeing the first pre-orders come in before our wider launch has honestly made our whole team really excited. Thank you to everyone who shared feedback, tested samples, or told us what could be better.

As a small thank-you to this community, you can use code EM11PRO03 for an extra discount during pre-order.Pre-order link

Thank you to everyone in this community who shared feedback, tested samples, or told us what could be better. EM11 Pro exists because of those conversations, and we’re grateful to keep building with you.
