I purchase these knots to use in the brushes I make. Both I and my customers love it. Knots are difficult to describe given all the nuances and various descriptive words which are all subjective, but the tips are super soft. They feel amazing on my face, yet the inherent design of the knot provides good backbone for soaps and creams and lathers it up very well. The fibers not only look similar to a Badger knot, they function somewhat similar to Badger for lathering. Of course, no water absorption is possible with nylon fibers, but the preparation and cleanup of synthetic knots is worth the tradeoff for me anyway.
I read the other review concerning the loft. To me, it made no sense what he was saying. Most brush makers will vary the hole size and depth for the knot socket hole to meet the requests of the customer. I am not aware of any required 20mm depth or a 20mm "standard depth." When I set this particular 26mm knot, I was easily able to set it in a 1 1/8 inch (28.6mm) diameter hole and only 12mm deep. That was more than enough to hide the manufacturing glue that shows on the knot. I was able to achieve a 53mm loft without any issues at all. Personally, I think this knot performs extremely well at the maximum loft (52-53mm) and I personally would see no reason why you would ever need to lower it into a deep socket hole, in fact, I think it would NOT function well with a tight/low loft.
I give it a 5 star rating because it really is a knot that you should experience whether you prefer badger or synthetic. If you like synthetic knots, you will love it. If you prefer badger brushes and want to try synthetic for travel, the 20mm-24mm version of this knot could be ideal for your travel needs.
