robinb, I have used it in the past when I was doing RA4 but it has been a number of years now since my last RA4 print. However I used it as a print brightener as I have always had running water for prints
Mine was bought from Nova Darkroom when it was still in Warwick so a long time ago. My instructions say that it will only do 20 10x8 prints at 1+3 without any water at all and Nova recommended that a dip and dunk in water was used whereby the capacity increased to 40 prints so even a quick dip in water helps
What I cannot now recall doing is comparing a wash in running water only print was any less bright that one done with a full wash and then brightener
It would seem to work OK in place of water otherwise why would Nova risk making the claim but without any water it might be quite expensive.
On the other hand at 1+9 dilution a 1 litre bottle does 200 10x8's even without water which is quite a lot and if water is awkward in your set-up it might be a price worth paying
