I have 32 of these still hanging off a RPi, along with a Butterfly Labs
Jalapeno that runs at ~7.5-8GH hanging off another Pi.  Grand total of 
~18-20GH.

I've recouped my investment and then some.  Not a HUGE profit, but I got
in at the right time (ordered the Jalapeno for $125 or whatever in
October? of 2012, it was finally delivered nine months later.  

I'd been playing with mining with a dual-AMD-5850 PC rig (which I sold
to a friend for what it cost me), then switched to the Block Erupter
sticks while waiting for my Jalapeno.  Once I switched to the Jalapeno
and the sticks, I used any earnings to buy more block erupters until I
had a total of 42.  Gave two to friends.

All together, I'd say I've made maybe $500 over the past year on top
of hardware costs and power expenses.  

If I'd had more money to put down for BFL ASIC gear in late 2012 I could
have made a lot more, but eh, hindsight, etc.  

It's been a fun experiment and still brings in about $100 a month at
this point.  That's gradually declining with the rapid raise in BTC
difficulty level, but right now it's a small pile of gear that fits on
the seat of a folding chair and makes almost no noise and uses
negligible power compared to everything else in the house.  I've got it
all running off a single ATX power supply.
