Hello all,
I sell PF's PHD and PMK here in the UK and was drawn to this thread by one of your members.
It was more than likely the PF kit sold by myself that had the over-weight chemicals that Ian G refers to above - a very good point raised as I had been using the chemicals without measuring them as well.
I have been in touch with Sandy King about the weight issue, giving him the weights of the chemicals of three kits I weighed myself.
All three kits weighed had more than the quoted weight on the instruction sheet, the more concerning examples were a Phenidone sachet having 1.46g (should be 1g) and Pot Bromide having 1.6g (should also be 1g). I too would have considered these an appreciable amount more but, Sandy's response was the 'difference in weights would not impact significantly the results very much, if any, in practical testing'.
I have a new batch of PHD kits, which PF have assured me have good quality Phenidone (though the weights may differ from that on the instruction sheet!). They also assured me that my original batch of PHD was good quality as well and I have received no reports of poor mixes. I have a sale on at the moment with many products including developers, fixers and toners reduced -

I hope this clears up some of the above concerns.
