It's the shit. Gets you good n tan, seems to burn fat, and gives you boners.
The downsides: can make you nauseous--never happened to me, but I've heard others report it. Also, I get super flushed and look like I have a sunburn for 1-2 hours after shooting it.
As for the freckles/moles, yes, some will appear but this can be minimized by using smaller doses. I used to do 500mg every night and I got way more freckles than now, when I'm just doing 200mg before going out in the sun.
Either way, the freckles are temporary and won't detract from the overall look. It's more of the shock you might get when you look closely in your face and see freckles that had never been there before.
