Price: You will pay £44.26 (excl. VAT) for this brush; this is not cheap but far from expensive either, and will not regret it (or at least I did not).
Quality: The brush is very well made, from the handle to the bristles. I was impressed by the quality of this brush, which didn't loss a single hair.
Density: The density isn't the strong feature of this brush. Even if the bristles are of a very good quality, it is not packed as tight as it could be. But the water retention is nonetheless excellent.
Stiffness/Softness: OK... I will not discuss this point. If you are buying a Vulfix, you know that you are heading for a SOFT brush; don't complain if you want a stiffer one... you have been warned
Ergonomic: The handle, built in a faux ivory design, is beautifully made and very ergonomically friendly; I really like it. But be advised that it stands 60mm high... so if you have small hands it may be to big to be really comfortable.
Latherability: The Vulfix 2235 is - in my opinion - a wonderful cream brush... it is just a gorgeous brush: You don't need a lot of cream, just "wet" the bristles, a few swirls in a bowl and... TADA ! lather up to the wrist...
Conclusion: this is a very good brush, and you will not be disappointed by the money spent to buy it. If you are looking for stiff bristles brush, go away, this brush is not for you; if you are looking for a soft brush, you have already found it: a Vulfix 2235 super badger.
I have the same brush and it is well balanced to whip up lather quickly with soaps and creams. It could be a little denser, but I am very happy with its performance. It doesn't consume too much soap or too much cream in making great lathers.
