You haven't really qualified "piece of garbage", so I have no idea what actually happened, but I will note that charger manufacturers have pulled some bait-and-switch tactics in the past. I bought a battery charger based on an NLee review[0], and was very satisfied. A friend later asked for a battery charger recommendation, and I went back to that very review and found that they'd started selling a "revised" model under the same listing, that was basically worthless. Something similar may have happened to you.
