I'm unhappy to report that I was scammed again on eBay, by 3 different sellers in a row (I highly suspect it's one same person), all selling bike lights for attractive prices. Like the previous one, they had good feedback since last fall until very lately when almost every feedback is complaint about scam--no shipping or no reply. They have some 400+ feedback and 96%+ positive (could be 97~98% before the recent negatives). I suspect they already had the plan in mind when they started selling with a new account: sell for 10 months and get enough positive feedback, then finish with fraud.
I didn't expect to encounter so many scams within such a short period. Lesson: don't be fooled by too attractive prices.

Since this thread was revived anyway, I'll say that a feedback rating of 97-98% is NOT a good rating. It is actually really bad. I won't buy from a seller with less than a 99.5% rating, and actually prefer higher. Yes, there are mistakes that are made, but that shouldn't affect your rating if it is fixed. When one in fifty has a bad enough experience to leave a bad rating, you know they aren't really looking to satisfy the customer. I usually allow a little slack from the Chinese sellers only because shipping can be a nightmare and outside their control. I'll look at the negatives and adjust if there are complaints about that.
