If a Razorock container is broken they refuse to replace it due to shipping. They refund your $2.50 but it was a gift set so my brother-in-law received a defective products. So I unfortunately shop elsewhere. Too bad their economy soaps are marvelous.Maybe the GC. 68SB. But what I love about the Merkur razors I have yet to find a blade they don't like. They work great with every blade I've tried. But I prefer them with sharper blades like the Nacets.
IMO the problem with the RazoRock offerings if you buy them from Italian Barber & you don't love them you can't return them. Which forces you to sell them or trade them on a forum. Before I bought the 30C I was tempted to buy a Lupo .72 but decided to pass. Since there are times my RR GC disappoints me with either the .68 or .84 plate. But YMMV.
What I really love about the 30C is the black resin handle. I find it extremely grippy & feels like a rubber handle. Can't complain about the shave either. The Merkur 33C, 34C & 30C just work extremely well for my every day shaving needs.
Would never recommend a Fendrihan... had a MKII for a couple years, even tried revisiting it. So bad that I threw it in recyclables last year as it wasn't deemed good enough to even PIF
Mine arrived with a defect that probably would have made it behave badly like yours: the top cap was pretty badly saddle shaped, almost like someone tightened it so hard that it bent the cap in towards the middle.
But customer service was good about it once they saw my pictures of it and sent a whole replacement razor, which so far (one shave) seems to be in good shape.
Seems like the head being cast metal instead of machined gives them extra QC issues.
Mine was fine that way. Found that the casting method made the bar unpleasant. Not smooth at all and since I shave steep it was very very uncomfortable, the razor is also aggressive.
