[TowerTalk] Heat from nearby lightning strikes...

Since the company is based in Taiwan, I'll bet dollars for donuts that no one "wrote" that ad; rather, it was run through Google translate and that's what comes out when you translate technical Mandarin to English with software that speaks neither.

Attributing technical incompetence to such foreign companies is just so Imperialist running dog. 

Reminds me of the Dave Barry column "Read This First". A sample: INSTRUCTIONS: For results that can be the finest, it is our advising that: Never to hold these buttons two times!! Except the battery. Next, taking the (something) earth section may cause a large occurrence! However. If this is not a trouble, such rotation is a very maintenance action, as a kindly (something) viewpoint from Drawing B.

Gas discharge units "do work", but unfortunately their advertising department, or whoever wrote the add, has no understanding of how they work.
That is enough to turn off knowledgeable "potential" customers.
IOW, that add probably cost them more customers than it gained.
