I used to use The Bearded Colonel, but changed to Cornerstone as they allow far more flexibility on blade delivery - which I very much like - and they use/source the same blades which are excellent. I have just one very small niggle that is the same for all of these multi-blade providers: the gaps between the blades are difficult to get completely clean so unless you shave every day (I don't) the gunk that collects there goes hard and makes for a very much less effective shave. I use an old toothbrush head to clean the blades each time but my wife constantly throws it away - yes, I keep telling her (she constantly forgets), and, yes, I have considered divorce (too expensive). Along with all the other products it would be useful if Cornerstone offered a small cleaning brush with their logo on it - I feel that this would not get thrown away and it would perfectly complement their range. If it wasn't for this, I would have given them 5 stars.
