S4'B1 is limited in quantity, as it is the first mass production after the development stage.
B2 will be available when our sales team get solid confirmation from our production team, and the quantity will be much better. Thanks.
If it's anything like the s3 then they used quantity where they should have used quality. They couldn't even get a unit with 2 blades out the door in working condition how bad are these batch 1 alpha testers going to get reamed. Bet they didn't include weeks of arguing with support and return time into their ROI calculations.
By batch 3 the price will be more reasonable and we'll know if they work as intended.
