I bought a cheap ($35?) front wheel for a CL flipper.
As delivered, it was quite true, with the expected slight flat spot at the rim joint.
However, every alternating spoke was about 1/2 the proper tension, with the other at 1/2 proper tension.
The spokes were 2mm short of the nipple flat.
It tensioned up quite easily, but short spokes can likely cause problems in the future with the nipples breaking.
It's kind of a shame that a factory that probably uses tens of thousands spoke per week couldn't use the correct length!
Else, it could have been a very "serviceable" wheel when tensioned properly.

Forgot to add- The bearings were nearly "dry" with what appeared to be a thin coating of a semi-hardening spray lube and too tight.
