I just got my Twine and I love it! I'm going to order a bunch for my dev team for Christmas. Anyway, I didn't see a forum for posting feedback and don't know when that will be helpful to you.
Quick comments: Setup was effortless, worked really great!
Made a test rule, emails sent without a hitch but SMS's didn't go.
Just FYI... keep up the awesome work.
I also set up the above with my email address, and have never received an email (Gmail account).
I have removed the batteries and completed setup again, but still have same performance issues.
Email has been working fine for me also (Gmail account)
... strange ...
