For me jury is still out for technozen as he never did reply to my emails regarding issues with a repaired unit. My mk1 still won't start even after re-synching both fobs. The instructions did not replicate what I was seeing or expected to see happening. So for a no show on communication I feel like I have been robbed.

We have to buy them through a specialist electronics importer, they're a nightmare to get hold of.
