Thank you. I've looked at some options. I felt the on-off button didn't work in my design (I did explore it).
I want to achieve something simple yet striking, that communicates at a glance that it's a top-of-the-line product, also that it's easy to use.
I've shown the latest design in both upper and upper/lower case type versions. All upper makes the 2 sit nicely below the other letters but you might prefer the mixed version.
As far as the wave goes, it added more complexity to the design and I felt it was superfluous. I must note that another designer has done this and I would have to steer clear of doing something that they own as a concept. I hope that's understood.
Any further feedback is very welcome.
