Yeah the plexible funding is usually a big red flag for campaign at igg, if they don't reach the goal they still get to keep the moneyz.

Another big difference, which causes the trust difference between IGG and KS, is that KS requires a working prototype, don't allow photorealistic renders (although a lot of campaigns have them) and if the product appears to be a scam or defy physics/thermodynamics they will shut it down. IGG basically has no moderation so there are A LOT of scam projects unfortunately.

Stil, Chen seems to be on the way to make a nice working proto before the end of the campaign, so should be alright!
