A rule of thumb: When ordering goods online, if something sounds like a scam, it probably is a scam. This is what one Malaysian man learned the hard way when he ordered what was sold as a penis enlarger and received, instead, a magnifying glass.

The man, known only as Ong, paid 450 Malaysian ringgits (about $140 USD) for the penis enlargement device, reports The Star Online. The package he received contained only the magnifying glass and a short set of instructions: “Do not use in sunlight.”

While Ong has filed a complaint with the MCA Public Service and Complaint Bureau in Malaysia, he has not yet come forward with details on where he ordered the “penis enlarger” from. Even if he does, the chances are low that he will have a legitimate case to sue.

It is especially hard if there is no proof of purchase, such as receipts,” Lawyer Alex Kok told the paper. “We wouldn’t know who to sue or where and how to sue them.”

Ong’s case is not a singular one. Thousands of dollars are lost every year by online scammers like the one who sold Ong the magnifying glass, and the complaints bureau says the con artists are not ones to discriminate among their victims.

“Men and women are equally vulnerable to these scams,” The chairman of the complaints bureau, Datuk Seri Michael Chong, told reporters.

Three people lost a total of more than 80,000 ringgits ($24,899) to these scams this year alone.”

A lesson to heed caution when buying things online, particularly those of the genitalia-enhancing nature.
