Love this product!

I came across this product by accident as I was waiting in line at Office Depot. This is such an ingenious and clever invention. I had been refilling my cartridges for years, with syringes, staining and spilling. This system makes it so easy, clean and fast.
The only drawback is that sometimes one color (in my case, yellow) runs out before the other colors, so I purchase individual bottles of each color on line and do it the old way for the missing color so as not to waste any ink.
