This is technically not an OSR device(since its linear) so the tag would be incorrect.
Note: I’m not a seller and this isn’t particularly my realm of expertise(marketing) but I have enough common and learned knowledge(especially after looking at a variety of devices that have been made recently(FleshyX3) or failed(syncbot)) to come up with some decent questions.
If you want to people to take a look at the device(to make their own or to buy): How does it compare to the current offerings out on the market? You’re competing with TheHandy, Kiiroo Keon, and the FUNSR1 that has an option for a twist. Atm all we know is it has high load capacity.
Whats the accuracy of the device? Whats the maximum/minimum speed? What are the methods of connection(bluetooth,wifi,wire)? How does it connect to the scripts?(intiface,multifunplayer,etc)What’s the power source? Can it be held comfortably or was it just designed to be used with a handsfree setup? If its a handsfree setup, whats the setup?
If you’re trying to sell it: What’s the target price? Will the user have to buy anything extra(like straps, power source, their own handsfree setup) How’s shipping? How will people pay you?(Paypal, Creditcard, Bitcoin, etc) What about customer service and troubleshooting for the device? Warranty? Etc.
If you need an example of what not to do it would be a good idea to look at the recent release of the Fleshy X3. A lot of people broke down their issues and concerns.
You would also have to look at what’s the market for a linear stroker with a high weight capacity cause I’m not sure if that was particularly high.
