There's a non-programmable version from superbrightleds.That "*yet to be released ST2 strober" looks a lot like the current units some of us have.

It's not a deceleration warning light using an accelerometer as is the ST SMB device.
From the Strober "site":
The ST2 Strober flashes your brake light when you engage the brakes yourself. The brake light will flash 4 times, then stay on steady.
So no deceleration activation. I didn't notice that bit when looking after getting an advanced notice merely from doing a configuration check. Along with that label pasted on the Strober it looks to be the same module as the Amazon version. No doubt made in China and sold under a bunch of names. I wonder what it would cost you to return it.
The plan was/is to do something similar. I have an LED brake light built into the plastic pad on the ST1300's rack. This was built and sold by a former member. I have a Strobes n More EMS LED strobe connected to my brake lights.I ran my centre high mount brake light and my top case brake light through the flasher module. I left my OEM brake lights untouched so that they do not run through the flasher module.
The tail/brake lights have been replace with "standard" LEDs. They don't need to flash. A deceleration light for the CHMSL in the rack would be nice. The Strober gets a hard pass being nearly identical to the LSC I've yet to install at nearly 7x what I paid for my flasher.
All this makes me wonder what's up with the STS site and management. An Amazon review stated the original company went belly up and this is now a different company with a different name. The Strober doesn't yet appear on the main site and complaints about customer service and ignoring the lifetime warranty are unsettling. This rebranding of someone else's product sold at a huge markup smacks of desperation at best and an outright scam at worst. It's all disappointing.
