“The build quality is solid, the device fully works, and I can both see and feel the thought and care that went into choosing quality components.”
“Short of this being in a retail box with artwork, branding and a custom foam insert you’d be hard pushed to tell this wasn’t a commercial product.”
“It does not feel like a fan project at all, felt like I received a device from an established tech company.”
“After receiving it, I was kind of shocked at the quality, it blew my other OSR2 out of the water. Overall, 10/10 great experience.”
“It’s full of little thoughtful touches that make it feel more like a piece of craftsmanship than just hardware.”
“Everything feels solid, precise, and thoughtfully assembled. The level of care here is honestly on par with (or better than) many professional companies.”
“It’s been exactly one year since I received my OSR2+ unit from Vespera and it’s still good as new. Built like a tank, and made to last.”
“Compared to the Handy, two months after receiving the OSR2+, I am of the opinion that it’s definitely better at everything. His customer service deserves an A+.”
“It’s so solidly built that I almost forgot it was 3D printed. All in all I am extremely satisfied with my purchase.”
“I would 100% recommend the OSR2+ to anyone considering either their first device, or a huge upgrade from the Handy.”
“The machine itself is solid and well printed — overall I would recommend it, 10/10.”
“Polished, powerful, sturdy, and simple to set up and use.”
“There’s been no company I’ve ever dealt with that has shown me this amount of love & support for their product as Vespera has.”
“The design was even more amazing in real life. You can just feel the effort and quality of the work — it exceeded my expectations.”
“The device itself functioned flawlessly and the build quality of the device was great too.”
“You can definitely tell he knows his stuff and it translates well to the quality of his product.”
