Kiinde twist for pumping and feeding?

[jennybeans]

Has anyone here used the kiinde twist system for pumping and feeding? I got a free sample set and a coupon for 50% off the starter set and am intrigued. We used Dr Brown bottles with DS and the thought of not washing bottles for E is pretty tempting. I'm going to try out the sample set and see what we think and if E likes the nipples with the set but also wanted to see if anyone had opinions..

The bags are more expensive than regular storage bags and they don't store flat. Those are the main reasons I skipped it.

I got it because I thought it looked great. Unfortunately my LO was picky with nipples/bottles and refused it. I still used the bags though for freezing and I would pump straight into them with my manual pump at home.
The bags don't freeze flat and they're a little hard to store due to that. But, I LOVED the screw top because I could get all of the milk out. Also they were easier for me to fill since I could click them into the bottle to stand up. In over 900 ounces of milk I also never had one bust or leak.
One thing to think about is DC issues later on. My DC had rules in place that they couldn't open the bottles at all, they had to be ready to go. So if I would have used these I would have needed lots of extra pieces to provide 'complete' bottles instead of taking advantage of the snap and go.
