We own both this model as well as the older model (purple top). Although both do the job of making diaper disposal easy and mess and odor free, the new model is better in most regards.
Pros
- Less use of plastic in the disposable cassette. The old model was a real environmental criminal
- Tighter packing of the diapers. We can easily get 20+ small diapers in the bin, almost twice as many as the old model. Further, there is a lot less bag used (probably 50% less) per diaper in the new model because of the improved wrapping technique
- No need to push the bag down to create a new drop zone for the next diaper - the lid takes care of that task
Cons
- There is still a lot of waste in the plastic cartridge
- The knob to turn the bag is a lot easier to use in the old model
Hints
- Turn the knob two full turns. It uses almost no extra bag but helps to create a nice tight "sausage"
- Push the diaper down far enough so the plastic fingers grip it - this will ensure that the bag twists above it
- When you tie a new bag, loop it into the bag hook under the lid. This will make sure that the first few diapers don't fall all the way to the bottom, wasting bag.
Update: May 24, 2011: As the baby grows older (over eight months now), this bin has turned into a real disappointment. The room that it is in has an odor, and opening it is displeasurable, and the odor that is present in the bottom (when taking out the "sealed" bag) is an eye-watering experience. I don't know of a good alternative, but since it is not doing its job very well and the inserts cost an arm and a leg, I'm knocking off two stars, so four stars down to two. I have no problem paying for things that do what they advertise, but this fails.
