I won't post a picture as it is the same as others provided, but I just received my Dynavap Gifts. I received a bronze-colored 2018 or 2019 M, along with the green DynaCase, and 7 fin tip. I signed up with the thought that I may follow through with the purchase -- I was interested but not completely committed financially on 12/7.
It was a great gesture by Dynavap. I appreciate the gift and will consider that when I make my next purchase.
To the first person or two who suggested the tips might be QC fails. I think that may be true. I see that mine can support a full bowl, but doesn't have two more grooves -- instead, it has one more groove and it doesn't look deep enough.
In any regard, I didn't pay for it. I get a chance to see their future product in beta, Dynavap gets to gauge interest in an actual production model of the 7 fin, along with garnering good will. There is no downside.
Ok, maybe there was one downside. Dynavap sent me the parcel via 2nd Day USPS. I just got it an hour ago. Kudos for USPS getting there before Christmas, but damn, it shipped on December 8th.
In all, very happy.
