The ink issue that is being talked about is the dye use for the plastic on the tips. After the first washing this is not an issue. The Razan sultan is covered in shag that apparently did not absorb the dye well enough and washes out if it gets wet.
these are the best hoses on the market. Backed by a good vendor that will replace any problem hoses and you are good. Sometimes the glue can become weak but taht is easily fixed with a little glue. Even with these issues they will last a really long time, never rust and can be washed if they pick up flavors. I own both.
