Thank you Zac for sharing your experience 
It was an honour to build your device, and I’m grateful for your support!
Since the last batch I’ve made some improvements:
- The bearings arms have been lengthened by 0.64cm– completely hiding the M4 rose joint thread.
- The large desk mount has been updated for improved stability and a more flush fit on the desk.
- All PETG adapter profiles have been revised and introduce ironing print technique for a professional finish.
- The chipset is now flashed at 330hz instead of 150hz– due to using Update Type: PolledUpdate instead of FixedUpdate resulting in a much quieter and smoother functioning device.

- Will be using Low Strength Sealey Thread Locker on all the metal bolts; still allowing easy disassembly of treated parts whilst securing the device against loosening and vibration.

Would anyone who has purchased one of these units DM me for a script test? I am considering purchasing and noticed there was a lack of twist scripts in the community. I wanted to make a few before I got one of these and had nothing to try it with. I have been working on a script with some different tests/styles that I want some feedback on before finishing and making more. Not having the unit, I don’t know how important certain things would be, like: 100% movement accuracy, exaggerated twists, effects for unique actions (tapping D on tongue, hand squeezes, or popping the D out of the cheek, ect) Should this be in it’s own thread or strictly worked through in DMs? Posted it here because of the relevance to this unit and compatibility with my possible future purchase.
Sent you a DM.
Hey MB after reading the review, I realized what you meant but i believe the figure of speech you were meaning to use is pull the trigger. Pulling the plug means not doing it/quitting

Thanks! I’ve updated the text, appreciate you correcting me <3
VesperaさんからOSRを購入させていただきました。
国外から購入した経験がありませんでしたし、個人売買にも不安があり、
注文を悩んでおりましたが、以前の購入者の方々の評判が良かったのと、
VesperaさんにDMを送ったところ、迅速な返答、丁寧な回答にとても満足して注文しました。
4/28のロットで注文、4/30に発送、遠く離れた我が国に5/8に到着。
注文から僅か10日で受け取る事が出来ました。
到着して驚いたのが、まず箱が綺麗に保たれていた事。海外便は箱潰れが多いと聞きました。
そして開封するとさらに驚きが！
なんと私の国の言葉で[手書き]でメッセージが書かれていました。感動です。
丁寧にエアキャップで包んであり、さらにアームが動かないようにラップで包まれていました。
スペアパーツなども、別梱包で包んでありました。
電源を入れるときはドキドキでしたが、無事に問題なく動作しています。
とても驚いたのが音です。
handyと変わらない印象です。twistも低速～中速でなら不快はなくとても静かです。
制振ダンパー？がとても良い仕事をしている感じで、モニタースタンドからの異音も無いです。
これで長持ちしてくれたら本当に完璧です。
普通の売り手は入金が済むと、返答が遅くなったりする傾向があると思いますが、
Vesperaさんは一切遅くなることはありませんでしたし、国の違いによるアダプターの問題など、Vesperaさんの方から心配をしてDMをくれたりしました。
また多数のリンクによる説明、解説をしてくださり、絶大な安心感を提供してくれました。
長文になってしまい申し訳ありません。
ただ、私のように海外からの購入や個人売買で悩んでる方には是非おすすめしたい方です。
今回購入させていただいて、OSRも素晴らしいのですが、
1番感じたのは、 Vesperaがとっても優しいって事です 笑
注意点として国によっては関税で15￡程度上乗せされる可能性があります。

Thank you, Gonta. I’ve already expressed my gratitude via DM, but I just wanted to publicly acknowledge it here. I truly appreciate you taking the time out of your day to write such an encouraging review. It was an honor to build your unit💙, and I thank you again for your support.
ゴンタ様、ありがとうございます。DMでも感謝の気持ちをお伝えしましたが、こちらでも改めてお礼を申し上げます。お忙しい中、こんなにも励みになるレビューを書いていただき、本当に感謝しています。あなたのユニットを作らせていただいたことは光栄でした💙。改めて、ありがとうございました。

So far — overall, I would recommend purchasing a OSR2+ from @Vespera especially if you are in the UK (due to import fees). Not only do you receive a custom-designed OSR2, he is always quick to message if you have any issues. I believe he cares about delivering a quality product.

Thank you very much OL. I really appreciate the review and endorsement! It’s my honor. 
Since the last batch I have made some major / incremental changes, they are as followed:
- The previous supplier made silent changes to the motors that I wasn’t happy with, so I’ve upgraded the driver motors to 9iMod 35KG Coreless HV. They’re much smoother, impressively quiet (seriously!), and cost about £12 more each. While the total BOM has increased by around £27, I’m keeping the set price unchanged for now.
- All motors are now secured with M3 washers for added stability.
- The Velcro One-Wrap strap has been upgraded from 30mm to 40mm width and changed from black to grey fitting the PETG colour.

Thinking about getting one when it drops… How much is shipping to the US, and where do you ship from?
Sent you a DM.
From google, i think 9iMod also make >35kg servos. Would you expect that to lead to a better user experience (eg. using heavier strokers) or reduced noise? Are you able to build such variants? Im curious what you would use if price were no object.
Hi dabbad,
Yes you are right, 9iMod do make higher torqued motors however I find 35/30KG to be the best for an SR application. Let me explain why I think so in full:
My iteration uses 2 35KG 9iMod Coreless HV motors. Together they amount to 70KG of total torque. The arms from the servo spline are around 15cm. Thus if we calculate using the Load Capacity Formula:
For two 35kg·cm servos at a 15 cm distance:
Total Load = 2 × (35 / 15) ≈ 4.66 kg
Realistic Safe Load
To avoid overloading due to arm weight, motion, heat, etc., we can apply safety factor/overhead of 2–3:
Safe Load ≈ 4.66 / 2.5 ≈ 1.86 kg
Even with a safety net we can easily drive around 2kg which is more than enough for any Fleshlight or Onahole. This equation doesn’t factor in the supporting Pitch motor which also helps hold the sleeves and reduce motor strain.
Therefore 35KG/30KG is sufficient however why do I choose this, would 45KG or even 55kg be better? Not in my testing, here’s why:
One of the most important things in an SR is low inertia and smoothness, and as you increase the torque, the servo’s internal gearing and motor mass also increase, which adds inertia. This makes the servo less responsive, especially with light loads — instead of moving smoothly, it tends to overcorrect, sometimes causing jitter or buzzing = more desk vibration. A 35kg servo in our application is usually better matched to ~1-2kg loads because it offers enough torque without being overly aggressive, resulting in quieter, smoother motion than something like a 55kg servo. Also higher torque requires higher power and a by-product of that is heat. In addition good coreless motors are buttery smooth!
A: I would stick with 35kg for your motor torque, 9iMod have made revisions to the motor and the quality has improved, I am really happy with them. I believe they even market them for Robot applications whereas the majority of servo manufacturers just factor RC car usage. Hopefully that helps answer your question. Indeed 45kg wouldn’t be much worse but the likelihood of a sleeve surpassing 2kg is minimal.
