Yeah, that's at most a v2. If the review has pictures, you can tell for sure. The v1 has a black dustcap and 2 vortex ports on the front. The v2 has no dustcap, but 2 vortex ports on the front. Both of these are also as deep as they are wide.

The v3 has no dustcap, has a slot port, and is as deep as it is tall.

I am the Doctor, and THIS... is my SPOON!
