This is my first experience with downloading an app after upgrading to snow leopard. I considered these reviews, and the comments for the other fireplaces as well. My, what a cutthroat dog-eat-dog world the realm of free and ninity-nine cent fake fireplaces is!
My highest hope for this fireplace was to turn it on upon turning in to sleep on what remained of winter nights. My first test of this fireplace disabused me of that notion when the nice crackling sound soon received competition from the sound of my macbook fan going on. I may be overcautious about this, but whenever my fan goes on I stop what Im doing until it goes off. I took a bit of a chance letting the fire go during a lunch break and there seemed to be no repucussions - but I will never let it go further than that. That said, the fire makes for a very pleasant short duration break. The break in the surprisingly long loop can easily be attributed to the momentary oxygen gasps experienced by real fires. A minor flaw is that the flames seem to blaze a bit unnaturally fast, detracting somewhat from the mellowing effect, but the fan issue had already precluded extended relaxation on my part.
Though the upgrade touted halving the file size, for some reason this didnt reflect in my remaining HD space, but I am still happy to have this app.
