Will these rescue an over-dried crop?

I let my buds hang-dry a little too long (they're up from 50% to about 55% rh now that they've been in the jars for a week). I just read about a humidifying device called Drymistat Humidifier Tube that looks like it might revivatate 'em. Anyway, I ordered a few. Anybody have any experience with these? I'm reading conflicting posts on whether you can re-humidify and cure bud that's been over-dried, but there really isn't much to lose. Comments?

EDIT: After some more reading, it turns out that the huge number of positive reviews for the Drymistat were all from cigar smokers with humidors, and that these things apparently nail the RH to 70% That's a bit wet for bud, isn't it? I'm gonna try these things anyway, but will monitor closely for mold. Still looking from comments from anyone at RIU who's tried these, or a similar product.

You will be able to rehydrate the buds but you will no longer be able to continue the curing process, once they dry you can not cure the bud again no matter what. I use a piece of wet paper towel or sometime apple or orange peels to rehydrate the buds, no need to go spending money on that stuff man.
