I've been shaving every day for years. Every session, same thing: razor clogs, you stop, you rinse under the tap, you keep going. Two or three times per session. Hair on the sink, water running, shaving cream drying on your face.

At some point I stopped accepting it as normal and started looking for a solution. There wasn't one. So we built it.

What it is: RINXOR is a compact, battery-powered device that clears your cartridge razor between passes. Insert the razor, it runs a cycle, you keep shaving. Magnetic docking. No tap connection needed during the cycle. Compatible with Gillette Mach 3 and Mach 5.

Where we are:

• 18 months of prototyping
• Utility patent filed with USPTO this month (Track One)
• Pre-launch Meta campaign running since early May
• Kickstarter on the way
• Shooting the KS video this week
• Launch: June 2nd

The honest part:

The hardest thing hasn't been the product — it's been figuring out how to explain the problem to someone who's accepted it as normal. 9 in 10 shavers stop mid-session to clear their razor. Most people just... don't think about it. Making someone care about a problem they've been ignoring for years is harder than building the solution.

22 days out. Excited and terrified in equal parts.

Happy to talk through anything — KS strategy, hardware prototyping, pre-launch marketing. What would you want to know?

Long-time lurker, first post. Sharing this here because this community has been useful to read while building, and I figure the honest version is more useful than the polished one.

The problem

I shave every day. Every single session, the razor clogs with hair between passes and you have to stop to clear it under the tap. It sounds trivial — but 9 in 10 shavers stop mid-session to clear their razor, and more than half do it multiple times per session. You end up with hair on the sink, water running, shaving cream drying on your face.

There's no good solution on the market. Rinse under the tap (wasteful, messy), shake it (doesn't work), tap the cartridge against the sink (damages it over time). Nobody had built something that actually addresses this.

What we built

RINXOR is a compact, battery-powered device that clears your cartridge razor between passes. You insert the razor, it runs a quick cycle, you keep shaving. Magnetic docking — the razor seats automatically. No high-pressure jets. No delicate parts exposed to the cartridge. Uses about 200ml of water per cycle.

Compatible with Gillette Mach 3 and Mach 5 out of the box.

The hardware journey

- Multiple prototype iterations before finding a mechanism that actually worked consistently

- Currently working with a prototyping partner before transitioning to a CM for the first production run

- Filed a utility patent with the USPTO this month under Track One (expedited examination) — can't detail the mechanism yet, but wanted IP secured before going public

- Shooting the Kickstarter video this week — hardest part was figuring out how to show the problem visually in under 30 seconds

I'd love input on from people who've done this

- Prototype → CM transition: How did you choose your contract manufacturer for a first production run? Where to look for them?

- MOQ: What's a realistic first-run quantity for a KS campaign in the sub-$50 consumer hardware space without over-committing on inventory?

- KS fulfillment US + EU: Anyone coordinating split fulfillment across both regions? How did you structure it?

Campaign goes live June 2nd. Happy to answer anything in the comments.
