Query: A true diaper champ

This system is great. I had a diaper genie and hated it. Having to buy special refills was costly and then at times when I would do the twisting it would not seal but instead cut the bag and I would have to start the roll over. This thing is great to just put diaper in and flip and no special bags. As for odor complaints I do not have any and if it is a problem put a stick up in the bottom. Great product.
