You folks may be way ahead of me on this, but I'd like to take a moment to praise Tinymight customer service (the ever-kind, ever-patient Joni) and promote what I think may be very _good news_ for those who have had button issues. I did, quite recently, and I have in the past. In fact I've had quite bad luck with the power switch.
Most recently I could not fix the issue on my own, and had to send it out for repair. Joni explained that they now configure the interior mechanism as a modular kit that can be easily replaced, and that this new component kit has given them no problem as yet. It's a fact that my returned TM2 switch feels sturdier and surer than ever.
As before, U.S. repairs are being handled by the estimable VGoodiEZ (who I believe sometimes makes an appearance on this forum), and I was able to have my beloved TM back in short order.
I hope no one minds my saying what is obvious to me, that in an area filled with much mediocrity, Tinymight remains a sterling example of excellence on every level.
