The installation was not too complicated and although in the first couple of days I had to check and reapply the Velcro, it finally settled. I wish that there was a better way to apply the curtain rather then these cheap Velcro.
After installing the cats were a bit suspicious about using the litter box but there eventually did.
The curtain keeps getting filled with fur due to the static material and it doesn't reach all the way to the bottom of the opening which is probably for the best since one of my cats is a high pee-er.
Overall great bang for the buck. Essential accessory.
