I've played with the Replug adapter a little, and I have to say that it does perform pretty much as advertised. It took a little nerve to try it out with my N810, but I eventually tried setting it on the little half-inch ledge on my workout machine and giving the headphone cord a good yank down. It came apart, just as one would hope. I tried it again, and again the cord came off, with the N810 hardly moving from it's perch. It probably wouldn't work if the N810 were just laying on a flat table, but as long as there is anything holding the N810 back, the weight thing doesn't seem to be an issue. Overall, it seems like a pretty good product, just with abysmal customer service. It's rather a lot of money to protect an N810, but ultimately, the real reason that I bought it is to protect my N900 (once released, that is). It's the sort of product that will hopefully keep on working for decades even, as long as 3.5 mm jacks don't go out of style. Anyone who's thinking of buying one, just let me know if you have questions.
