Immobilizer Waterproof Case -- Anyone tried?

I've heard the drowned Immobilizer horror stories and wondered if anyone has tried one of these.

Porsche Boxster & 996 Immobilizer Waterproof Case Enclosure

Looks interesting, but my engineering brain has a problem with the method used to seal up the cable ports. You essentially work a big wad of silicone sealant into the wire bundles to seal the box. So...the effectiveness of the seal depends on how well you work in the silicone, along with an assumption that the silicone will never dry out. I'm skeptical...

Alternatively, wondering if anyone has ever attempted to move the box from it's vulnerable location to behind the seat on the bulkhead, or maybe simply elevate it at it's current location. Obviously, making sure all your seals and drains are functional is the first priority, but coming from a military aviation background, I like to eliminate the potential for single-point failures, if you know what I mean.

I installed the water proof box in my 02 base. The hardest part of the project was pulling the drivers seat. You do indeed have to seal the harness's with rtv. I believe it is cheap insurance.

I installed one about 3 months ago. Pull the seat, take out immobilizer, put circuit board into new waterproof case and seal with ATV silicone. Easy! Worth the piece of mind. Just use lots of silicone around the wire bundle and it will seal up nicely.

The company that makes them actually posted on this forum a while back, you can seem more info and thoughts on it here:

I decided I didn't need one because I don't park outside enough to be worried about water in the cabin.

Appreciate all the feedback!
Wish there was a way to move that thing out of its vulnerable location, but I'll assume the cable runs wouldn't allow it to move very far. The box is obviously a much better solution than the plastic baggy approach.

it can be moved, I'm told....

If your up for pulling your loom apart...

ANd lucky...you can move it, so I've been told.

only place that makes sense is f-trunk or in dash, I think?
