The next batch are due in this month at Shaving Time. Would suggest you contact Dave there to make sure you get an email alert for any presale as I'm guessing they're going to sell out in minutes again. I got an alert for the 5pm PS half an hour before and pulled the trigger at 5.01pm.
Extremely pleased with the razor, wonderfully smooth yet efficient and all the early niggles of V1 and V2 have been addressed. The free pack of Willys it comes with are unopened in their box and, I would imagine, likely to remain so for the foreseeable future.
