1 out of 5 eggsBeware of this lil' feller

Pros: There was nothing good about the unit I purchased ( Did not know at the time it was available here too )

Cons: Unit immediately smoked and blew my cars 15A fuse the moment I turned it on. No load was yet plugged into the unit. Could hear something rattling inside. Took it back to the store I bought it from for a refund.

Other Thoughts: I wanted a tough, rugged, *metal* pure-sine wave inverter ( Look them up- not for everyone but they are about as good as you can get ) but I fell for the low, low price. You get what you pay for. I'm saving up for what I wanted in the first place again somewhat wiser than before.
