I ordered this kit so that I would have a second one - one being used and one being cleaned. The tubing on this is a little bigger than my other set and is a little more difficult to attached to the external catheter. But, it works and I made a discover! I'm new to this so the tubing was always a problem. There was always residue inside the tubing that was impossible to reach and clean. It literally made me crazy. The little bottle of Uri Clean that is included in this kit was the secret. It takes next to no time now to get rid of all of the urine residue inside catheter tubing ... all of it ... with absolutely no effort on your part. I have to wonder how long it would've taken me to find out there was a product out there to do this if it had not been for this kit. All companies who sell these things should make it a point to mention Uri Clean in the description as the best way to clean catheter to bottle/bag tubing.
