Thank you for the panel which was quick and easy to install with the door hanger. (Though I need to do a little DIY to put it in a more convenient position on a wall. After just three sessions on use the stiff neck I'd been suffering was cured and I can now twist round to see traffic overtaking me on my bike. Also appreciate your attention to the detail of emf emissions which give a negligible reading on my Cornet meter. I look forward to the next purchase.
