The discussion centers around a free units converter available at Kamlex, which some users find useful for occasional conversions. However, it is criticized for being a poor imitation of Omnicon, which is regarded as the superior converter. Key complaints about the Kamlex converter include its bad user interface, lack of customizable units, absence of information about units, and the inability to manually add new categories of units. Additionally, there are claims that it is not free, contradicting its advertised status. Overall, Omnicon is favored for its functionality despite some negative opinions about it.
