Безопасен ли inkowl.com?

Their refillable cartridges that I bought for my Epson NX-200 are nearly the best thing since sliced bread. My only grief with them, is they actually have to be removed from the printer for the auto-resetting chips to reset, introducing air bubbles into the ink path that have to be purged. This is contrary to the video on the site, and the video that helped me find them on YouTube. I have doubts about the video though, as it sounds like it was made by a very liberal arts major, who really didn't understand the process. Seriously, listen: ***** Anyway, this aside, they've got the best product of this type going. I would patronize them again.
