My 2 year old decided to play with the mount for my TTv1 yesterday, and ripped off the sucker element. It's looking rather ill and I think I need a replacement. From checking a well known online website, I see the it's possible to buy a "genuine" replacement for £25. There's also a "professional" replacement that looks similar to the genuine thing for £10, and a Duragadget air vent mount unit for £5. Anyone have experience with either the Duragadget or Professional ones and care to comment?
