Another vote for Neckgen. Got mine before Rev came out. Once installed almost invisible except when trying to back out of the paddock and then you can really feel the teathers.
There was a thread on this on trackhq (No more Necksgen.....)
and here is data complied by one of the posters: http://www.r-series.org/rsd/HNR2012.html

I have the previous version of NecksGen. I got it because it was adjustable, much less $ than the adjustable HANS, can be used with 3" harnesses and available locally. The extra lateral support was a bonus. At some of our local tracks, I have to adjust how I leave the pits to ensure I can see down track with it on.

If you are planning on instructing, the stand alone Simpson may work better. It can be used with student's 3 point DOT seatbelts, where the NecksGen requires a harness.

newold_m: Great link to TrackHQ, somehow missed that one. Reading thread now, Props sir.

Just to be clear: those of you currently rocking the NecksGen product are using the original, not the Rev, correct?

Not planning on instructing. I'm qualified to turn a wrench or a wheel, not much beyond that. Point taken though about the DOT seatbelts, though not sure its going to be much of an issue, 3" GForce 6pt on the menu right now.

Interesting, in the TrackHQ thread Emilio said he has a Rev as of 12/9. I may prod him and see if he's had a chance to do anything with it yet.

I personally feel this arguement is irrelevant as a 3 point by design... will not create a situation where a basilar skull fracture could happen.

A basilar skull fracture is not the only possible brain injury racers might want to be aware of. There is some talk that the same sort of compounded minor damage that fighters (mostly boxers), pro wrestlers, hockey players, and football players have suffered later in life might also affect drivers that have seen multiple concussions.

Right, previous NecksGen, not the Rev.

A HNRS does not protect you from concussions. That is what a helmet, SFI padding, airbags and oem soft surfaces are for.

Everything I read when preparing for this purchase a couple years ago suggested the same. I bought my hybrid pro rage because it tested better than hans and was the lowest priced SFI option at the time, not for the 3-point seatbelt factor. I never wear it while instructing in cars with 3 points.

I knew something was brewing in the necksgen case, and I was right. Courthouse News Service It does sound like they're not going to be able to sell them anymore without another re-design.

right... as was stated earlier in the thread and in the trackhq thread... necksgen's previous device is no more due to patent lawsuit from leatt which caused a revisit of the stay on the defender. This is what has lead to the necksgen Rev as being a full re-design that doesn't infringe on the original HANS lawsuit that killed the defender... or the Leatt lawsuit that killed the original necksgen.

I will throw my 2c in here, but it might not help much...

I've only ever worn HANS (a couple different versions), I've never tried any of the other HNRs out there. When I was shopping I considered the defender and the rage, but in the end I bought nothing and continued to "borrow" HANS.

I've done a lot of W2W racing, always with a HANS, most with an old one that was recertified. The old one I used didn't have the "wings" the new ones have to prevent the belts from slipping off, so I put some grip tape on the surfaces. Problem solved.

I've also been in two fairly nasty accidents, one a roll over at HIGH speed, the other straight into a tire wall after brake failure, was probably going 35-40mph by the time I hit the tire wall (2011 NASA Nationals HC1 race...). Both times I was wearing and old style, shitty HANS. Both times I was perfect the next day, no soreness, no sore back or neck, no issues whatsoever.

I can't say the HANS is better than the other products out there because I haven't tried the other stuff. I can say that the HANS has worked perfectly well for me, I've done a lot of W2W racing, and I've had plenty of opportunities to "test" the HNR...

HANS had a sale on it's "Sport" version recently, it might not still be going on, but at the time you could get an entry level HANS for I think about $600.

Maybe there are legal/political reasons for it, but when I walk around the paddock at an ALMS or Grand AM race 99% of the drivers are wearing HANS...

Having a tall back and the need to use FIA seat (no custom Alu seat) the added height to the shoulder belt made HANS unsuitable to me, and the Simpson added some extra side support.

The Rev seams to be a mix of the previous NexGen and the Simpson device, sitting further back and not build that much height to the shoulder belt.

HANS is still used mostly based on tradition and the use of it in high end Formula series, in cars which have protections for all other directions built in.
Simpson now own HANS and will not put more R&D in that direction (new colors maybe).

BTW, take a look at RaceQuip 6 point harness with pull up straps. I replaced my old GForce with these and I'm so happy I did. They're also available with 2'' web for Hans application and I recommend it with Sport II.

I will never drive again without my Hans and this harness, it's like a Scroth in term of comfort but at way lower price tag and still FIA app....

SafeRacer.com still has them on sale for $600.

Anyone have updated info on this. I'm looking at the rev and hans sport. Essentially the same price, both sfi certified.

Here are their respective videos.

Hans

i'm interested in the new leatt unit myself. (current owner of a necksgen not a rev).

Same here, the Leatt looks very interesting. Has anyone actually tried one yet?

Saw this review the other day:
