This product works flawlessly with my Windows XP and OS X - just plug it in a USB port or use the included software. The print quality is very good and I am quite satisfied at this price. I've been using refilled cartridges for about 2 years now from various sources but found that most of the time, ink dries up within 1-2 weeks time when you refill them. These re-manufactured cartridges are great to buy, they don't leak as far as I'm aware and work perfectly.

Good Review

This was a pretty boring book. I finished it but didn't care much for it....I'm afraid that the sequel will be no better. Not really great at all.

Good Review

This was the only set I bought of this type when making home decor. While they have a cool futuristic design, they're not practical because as we all know, you can never fill an 8+ oz. container without overflowing it. We also found at least one unit that had poor quality. Some were cracked or chipped. Other units leaked. So many other people recommended these to us and it seemed like just what we needed.
