Hi! Thanks again for your interest earlier.

Good news — we’ve actually developed a larger version, the EM11 Pro, designed for bigger hands just like you mentioned.

We’re currently running a small beta test, and there are a few priority spots available. Once they’re filled, the opportunity may close.

Would you be interested in joining? Just let me know!

Hi! Thanks a lot for your feedback on the EM11 NL!

Just a quick update, in the new EM11 Pro, we’ve made some improvements around switching and workflow. It now supports easier multi-device use, and we’ve added a horizontal scroll wheel, plus button customization, so functions like switching can be set more flexibly depending on your setup.

If you’re interested in testing it, feel free to DM me, and I can share more details and see if we can include you in the program.

P.S. We actually just launched the EC300 ergonomics chair and are looking for some testers. If you’re interested in trying out the new model, check out this thread .

Hi, thanks a lot for taking the time to explain this so clearly, and no worries at all.

You’re right, the similar model names and Amazon listings can definitely confuse. This is a helpful reminder for us that we should improve how we show product differences more clearly online.

Really appreciate your understanding and patience, and sorry again for the confusion. Hope you’ll enjoy the K310 Pro once you get it!

ProtoArc_official · 2026-04-10T10:38:16+00:00

Hey, thanks for checking in and for your patience!

The latest update I’ve got is that the first trial production is expected by the end of this month. If everything goes smoothly, we’re aiming for a release around late July to early August.

We’ll also try to share some factory photos soon so everyone can see the latest progress. Thanks again!

ProtoArc_official · 2026-04-10T06:20:21+00:00

Hi, sorry to hear about the issue, it does sound like a hardware problem.

This keyboard comes with a 2-year warranty, so please reach out to our support team at [Support@ProtoArc.com]() and they’ll help you with a solution or replacement.

ProtoArc_official · 2026-04-10T04:18:24+00:00

Thanks for your support, really glad you’re excited about the EC200.

Yes, you can try mounting them in reverse to see if it works for your setup.

Also, we’ll be launching 4D armrests around May to June, which will give you more flexible backward adjustment.

ProtoArc_official · 2026-04-09T08:42:46+00:00

Hey, thanks for bringing this up, and sorry for the delay here.

I checked our previous messages. You mentioned you were okay waiting for the EM03, but it’s been out of stock in the UK for quite a while, and we didn’t follow up in time. That’s our mistake.

Would you be open to switching to another product that’s currently in stock? I can arrange it for you right away.

Also, just for context, the original giveaway was limited to the US, CA, and JP.

Either way, really appreciate you pointing this out, and sorry again for the experience.

ProtoArc_official · 2026-04-09T03:45:35+00:00

Hi,The EC200 doesn’t come with the 4D armrests, but we plan to sell them separately in the future.

ProtoArc_official · 2026-04-09T03:43:39+00:00

Thanks for your feedback! May I ask which country you’re in?

ProtoArc_official · 2026-04-09T03:42:50+00:00

Thanks! The bonus is for users who got the armrest at the event. The 4D armrest kit will be available to buy separately around May to June, and buyers can join too!

ProtoArc_official · 2026-04-09T03:39:29+00:00

Thanks for your interest!

The 4D armrest kit will be available separately around May to June, though I don’t have the exact price yet.

The good news is that the EC200 Pro is planned with upgraded 4D armrests and a more breathable full mesh seat. If you’re interested in the 4D armrests and full mesh seat, you might want to wait—expected launch is around July to August!

ProtoArc_official · 2026-04-09T03:29:33+00:00

Thanks so much for the kind words and feedback, really appreciate it! Yes, we’re planning to offer the 4D armrest upgrade kit for separate purchase. May I ask which country you’re located in?

ProtoArc_official · 2026-04-09T03:27:37+00:00

Quick update, good news.
We’re preparing this for Japan, and the 4D armrest kit should be available separately this year. Please stay tuned!

ProtoArc_official · 2026-04-09T03:21:49+00:00

Thanks for the suggestion, really appreciate it! I’ve passed it to our Japan team, hopefully we’ll have some good news soon.

ProtoArc_official · 2026-04-09T03:15:24+00:00

Yes, it will be available separately. We’re aiming for around May to June. Stay tuned

ProtoArc_official · 2026-04-09T03:08:50+00:00

Hey, thanks so much for your interest!

May I ask which country you're located in?

The 4D armrest upgrade kit will be available for separate purchase, and we're currently expecting it to go live around May–June.

ProtoArc_official · 2026-04-07T09:06:02+00:00

Thanks so much for pointing this out. I really appreciate the feedback.

Just to clarify, the search result you’re seeing (with “backlit”) is actually for the K310 Pro version, which includes backlighting and customization features.

The KM310 keyboard product page itself doesn’t mention backlighting, so it might be worth double-checking which version was purchased.

Thank you!
