I ordered a 10,,12,,14 pack from Amazon, 360, and an 8, 360 and a 16 Old stock. I was taking a chance since the Amazon site didn't specify 360 or other. But was happy to get 4 out of 5 that were 360. I also only paid 48.00 for all five heads. Try and send those back before you use them and try Amazon.
You will not beat this price. I will not guarantee 360 but maybe a phone call would help. the Amazon ad says shipped from Amazon not some Mom and Pop store
