Ho does this differ from D2?

Also, there is no warranty process. For any customer support you must contact the distributor in your country, which of course won't help you if you didn't buy the product from them. The 'Topeak head office' couldn't care less too.
Topeak, if you really stand behind your product then reply here and let me know how I can contact you and get a new gauge shipped to my home. Regards

I have the original one and it never works properly. Battery is always dead, I use it once every 3-4 weeks and litteraly I need a new battery every time I want to use it. Stay away from this please.
