I got my replacement set of space saver trim rings in last week and went to fit them in my van. Ugh. While not perfect, the driver's side can be sanded to fit better without too much trouble. The passenger side ring is a disaster. There is no way to salvage it and the fiberglass is so thin in sections that light shines through.
I've asked, and they've agreed, to send me out another set. Hopefully, these will go through QA before shipment.
I love the Flarespace designs, but these guys are leaving the barn door open to competitors.
