This shop exceeded my expectations and went above and beyond to ensure everything was delivered properly. The plugs I ordered were built well and look cool on my synth. I had follow up from the rep and the owner of the company too. I would recommend this shop and would buy from them again in the future. total world class operation.

Well made, Very nicely finished, works great! Came in a sweet durable thick Mylar zipped lock reusable pouch. Colored flat black on the outside with a clear product windowed on the front and a reflective silver lining inside. Very nice presentation and a very handy way to store the UVPs so they don't get lost in the studio or in your gig bag. Exactly as it was described, it's actually better than described. Very happy with the UVP.

These are terrific! I got them initially to use instead of dummy cables for Maths. These are so informative. I highly recommend the dual color, as they will show you positive and negative voltages. To that end, they can be kind of like a quick meter of behavior of an output. I think they will also be fun to use for added lights on active unused outputs. They also pair quite nicely with stackable cables, so they can provide a visual aid to many signals! Customer service is top notch: helpful and outgoing. Quality build!

These guys are great! - USPS not so much. My first shipment was crushed so badly in shipment that there were only yellow chips left in the bag. They immediately shipped out replacements with a small gift. Believe it or not, that was also trashed in the mail! The third package came carefully packaged in a box - with three Light Plugs and a Eurorack Whiteboard as gifts. Mind you, they didn't need to do that - the problems were clearly with the US postal system (that was a bit overwhelmed in early November - I can't imagine why). Still, these guys go above and beyond and their products are well made and very useful (I highly recommend the Light Plugs!) Thanks guys!
