Jenny Kirk runs a youtube channel reviewing/reporting on model railways

Nick and I spoke to her at Ally Pally and she offered to do a review of OOLS.
We suggested to her that she should review it as if it was a new release with no baggage of arguments one way or another. We would ask that if she concludes with a negative review, we have the opportunity to input our experience before the final publication.
I have a dozen or so Mallard sets and would happily lend one and send it but I am not sure that any of my locos work "perfectly" ie faultless green AND red lights, good whistle, trouble-free reversing. I am not sure either that we have a Club loco that performs "perfectly" either. None did at Ally Pally.
I do have several brand new never run locos but I am reluctant to devalue any of those but I will check out my used stock in readiness.
First though, are we happy for her to do a review?

In principle I think it good idea to promote live steam, but I would not do it the way you are suggesting Adrian. I think we’re asking for trouble sending her one in a box and leaving her to it.
My suggestion would be to do this in a controlled environment, talking to Nick this morning he tells me she lives not too far from where we plan to hold the summer meet. Invite her to that, show her and let her try more than one loco on the club layout, demonstrate how much better they are on a reasonably sized layout, also demonstrate the advantages of live drive etc..
