I'm surprised this is struggling. I was in as soon as it opened because it looks brilliant.
I can't help thinking that the shipping from the Far East thing might have had an effect. There's been talk about it on other forums, and although it was always stated it would be shipping from the Far East, the info was buried at the bottom of the Kickstarter page. Once word got out, a few people were annoyed they were going to have to fork out an extra 20% to import it.
I still think it's amazing value with the 20% added but it would have been a psychological hurdle for a lot of people, especially as it's a British company and the 6BB shipped from the UK.
This is just my feeling, but I really hope it gets over the line.
