We use the set for about 3 weeks and our little one, before drinking rather lazy, loves it.
For the very small sucker he was too big, so we started with the 2nd article. This is cross-shaped cut, so children have to suck, but not to spill when turning. The cup is very light and easy to grip even through the great idea for the kids.
Our son (6 months) can keep him alone, so even at night, if he is thirsty, access. A big plus because we can go back to sleep :)
The attachment with the integrated straw makes a great impression (not tested). When spinnig he disappears in the bottle, losing so impossible.
Although the set is a bit more expensive, I would not hesitate to buy it again, it only has advantages.
