It says "Tom Tom" plus the Logo on the packet so I am lead to believe its a genuine part. It certainly works well and is smaller than the original which is good. The original only lasted 12 months so if this does, I will be well pleased for the low price.
I have a very smelly pair of old faithful trainers. I wanted to keep them and the Odor Eaters spray does a good job of making them smell better. Just don't breathe in as you spray them or you will regret it. Need to spray every time I use them so could be a bit stronger please.
