I sent my two year old unit in a couple of weeks ago along with a check for $75.00 and Ideal sent me a brand new one with the updated firmware. The circuit tester is more of a convenience item for me, which I do actually use every once in a while, so I thought it was a pretty good deal.
The last time around, Ideal replaced it for free, but I imagine that is getting cost prohibitive with the frequent tweaking that AFCI manufactures keep doing to try and make their junk science work they way they claim it should.
