Not really - there may be different builders, or “forks” of the original OSR2, but they all work pretty similarly. I try and keep true to the original open source geometry so accessories are compatible. Others have gone to try and make them more compact or larger, but for the most part, they’re all the same under the hood.
OSR has 2 servos, allowing the unit to move up and down like the Fleshlight Launch or Handy.
OSR2+ has 3 servos, allowing the unit to move up and down, tilt forward back, and tilt side to side.
SR6 has 6 servos, allowing the unit to move up and down, front to back, side to side, and tilt.
Here’s a response to a previous thread discussing OSR vs SR6. I PERSONALLY prefer the OSR2+ (which is why I’ve evolved it and build it exclusively), but everyone is different.
Yes, I ship to Germany. Contact me for a shipping quote - I need a physical address to calculate it, but it’s typically around 60-80 dollars.
Doesn’t require you to be a wizz, but having some tech experience is helpful. If you’re just looking to get into the “toy” realm, The Handy is a good starting point. I don’t want your first foray to be something that is a bit more DIY than you’re expecting. Just want to be clear about that. I do have a setup guide that I share with my customers that helps, but it definitely requires some knowledge of computers and tech-common sense.
