Finally got these to pair on my Mac, and I'm still seeing the same consistent behavior of the second Twiddler disconnecting followed by very long reconnect times or outright failure. Seems more likely to happen if I use the mouse, but also occurs with just keystrokes. I've observed this on multiple OSes/phones/adapters/locations as I've reported in the forum and on the phone.
@Tony Can we just acknowledge that the Bluetooth stack on the Twiddler is buggy and please stop blaming everything else? It's embarrassing - you've got a great product and I'd be happy to pay twice what it currently costs if it actually worked as advertised. Instead I'm looking at building a custom device because I'm at my wits end with these problems.
