Watched from the sidelines as Jane invented an early version of Sugru at college in 2003/4.
Everyone I knew (and me) thought she was completely bonkers, developing a weird substance that didn't seem to do anything but make a horrid mess of well-designed objects.
Saw how doggedly she persisted for years to get it off the ground, eventually winning me over (in theory) for the main use cases.
But still, as a hard-won fan with 15 years of anecdotal observation turned admiration, and as an accomplished DIYer and general proponent of fixing things, I couldn't find a use for Sugru in my life.
The real story here is a major life effort, not a crowdfunding over reach.
