When it comes to multi-axis or theHandy2 I sorta always come down to the same consensus. If you don’t have a single-axis device or are looking to replace a Handy, just grab the Handy2. But if you’re currently satisfied with your Handy(and not selling it or tossing it)(cause why buy a marginal upgrade for something you already have that isn’t broken) or if you’re looking for a new experience then look at the multi-axis devices. Its an entirely different experience going from single to multi-axis.
The OSR2 and SR6 are not handheld devices and require a mount. You can mount to a desk or you can buy a monitor arm with the vesa mount. As long as you can attach the monitor arm to a sturdy enough surface you can basically use it anywhere. People have mounted it to their beds with the arm. People have also mounted it to a laptop stand so they can use it in bed.
Anyways.
If you’re looking for more of the same but better, Handy2 will probably be fine. Its an improved single-axis device, but its still single axis.
If you want something new and different, multi-axis. Everyone keeps asking for a twist receiver for the Handy2 because they want to add another sensation to the device because there’s only so much you can do with just up/down.
