I will try mine out and see if the IR drops after I get a full cycle on them. I saw that on a recent set of SkyLipo's which showed a high IR initially then dropped down after I cycled them.

Oddly enough, the dimensions on my packs seem to match the published dimensions for the 5800's........ The weight is slightly less, but the published weights are always high. I'm thinking these are 5800's with a 5000 label stuck on them.
