I don't think so because this has really worked out well (to the majority of users comments). I would however, if I were to change anything, come out with a little different design unlike the traditional generic clamshell, but would surely satisfy anyone who likes that particular configuration. It would have greater ease. Already have that design in our files for future.
For myself, the top priority has to be performance and reliability with the high performance equipment (ETM) because a large majority of our customers have gasoline TM's, or have had them, or can't afford them. They do not want to go backwards by purchasing a traditional portable that only produces board line and sometimes minimal results. They all demand similar results and many add optional gas heaters on board. Results are amazing.
I have been in this business, as perhaps some reading this, for a long long time and of course like anyone with "experience" one obtains that by having done somethings wrong, or not quite perfect or acceptable. No secret that we all make mistakes (not on purpose mine you) but having done that, it really makes us better and helps us improve our services and products. Longevity in this Industry sure helps!
I am sure everyone can relate to that!
Thanks for asking.
