Public service announcement: Don’t order anything from laikeet.com unless you can wait several weeks for it. The registration address for the domain is in Pennsylvania, and they say your battery will ship by USPS, but what they actually mean by “USPS” is Hong Kong Post via the proverbial slow boat from China. Their advice for the resulting two-to-three-week delay? “Wait patiently.”
Don’t shop there. Don’t go there. Pay a dollar or two more and find an honest vendor who’ll get it to you this side of the Second Coming of Nikola Tesla.
