Converter lock up kits

Anyone using one of these?
Most internet info is so dated it's useless, but the consensus seems to be either a Stocklock or a Richards.
But some owners talk of having a Stocklock fitted at Richards ??
Both systems use PWM control and both have the two position switch for auto or low.
Wholesale automatics is the odd one out with dated technology, but again that info may have been superseded? Hard to form an opinion as Wholesale can't be bothered to reply to questions.
Some owners complain of P codes popping up, meanwhile others with identical system have no codes so driving style must have a big input.
Richards admits P codes can occur and offer a service where you post off your computer for them to modify. No more P codes.
From the YouTube videos, it sorts the LC200's auto perfectly.
