You don't keep to keep banging your drum MLT, you say it's an own-brand kit, fair enough but other sources have said that it could EITHER be an own-brand kit or an obscure manufacturer that hardly any of us have heard of, I'm hoping it's the latter as the quality could be slightly better but it won't really matter either way really, it's just nice to speculate.
You don't need to get anyone to believe you anymore, everyone already does.
