This refill kit, I can only recommend. I have already several months at home, and it has paid off. It is used regularly and is very easy. The first time it's been filled. The second time, simply take the container out, pull plug and knock the granules in the trash. Thereafter, the whole is filled and used again. Of course it is more time consuming, but this about 10 minutes I take like. The original container costs a lot of money. For the money and the fast checkout I recommend the product you.
