I still like the MT1, and have a few that work fine. The MT2 was a huge disaster for me. I never had one that actually worked with any reliability . The shortcomings on the MT 1 were no seamless splits (a huge consideration) and short internal battery life. I use external. I have an adapter for trs to 3.5mm that sits atop the MT and uses a button battery. That worked great, but today there are better sounding options. For me at this point I mostly and only occasionally use it as a backup bit bucket for some shows just to keep them going. There are just way too many better options. As a bit bucket as long as it's not one long set, the unit is small and works great. That said, if I didn't have them from those early days, I'd never recommend one with today's options. It requires running it a certain way, and deviating can mean a ruined recording.
