I signed up for email notifications at the end of October, and received a marketing email about it on December 3rd. When I hopped on the site, it was available for purchase and so I ordered it the same day. Unfortunately, despite no mention (that I recall seeing) of it being in backorder/production status, the order seemingly went through as if it was in stock. I checked the site about a week later and the intake was listed as out of stock/backordered. When I inquired ~2-3 weeks later why I hadn't received an update, I was told my order simply secured my spot in the initial production batch. I was told to expect shipment in mid-January. Fingers crossed.
I've had S&B products in the past and they're great quality. Once prodded about it, their customer service was also very responsive, transparent, and apologetic. I think this more so falls on their marketing. It could just be an honest mistake. To be fair, even if it was listed as backorder, I still would have placed the order, so I guess for me personally it's kind of a moot point.
