Promotinal at this small Wundereimerchen let me hope to find a relatively clean and bio-oriented collection of my kitchen waste. I regret to say, this bucket holds hardly what it promises. I have placed the bucket on my balcony. Through the air holes in the lid the smells flow out, so I, before we want to sit on the balcony the bucket always empty must. The fruit flies can also freely in the bucket and multiply rapidly. If you fancy a aqueous waste such as watermelon, the bag is ever biodegrade - still in the bucket - and runs every now and then. Conclusion: Highly expandable system, is not currently recommended.
