We had until 3 years ago a composter the FA Al-Ko (with about 500-600 liters) and were very pleased with the stability and the result. Unfortunately, this had become obsolete after 15 years and a new had to be found. Since we have a large garden, we also need a correspondingly large composter. Now there are at Al-Ko unfortunately no major Thermo composter more and we have been this time in search of a stable composter. That this is so difficult, I never thought. After we had already bought two other brands with which you can compost namely that the materials are kept so weak but all that these all bend and bulge after a certain time, we decided for the Thermo composter of Neudorf. After reading some reviews, where among other things, precisely this issue was raised, we were getting fulfilled our wishes considers with this product. Especially the double wall that is supposed to ensure more Stabilitä convinced me. The construction was done super quick and easy. If you're not one hundred percent but the composter horizontally establishes what is not always easy to implement in the garden, you have the same problem as with the other. Despite Doppelwadigkeit also these are relatively fast to, shifts, so that the lid will not close properly and the Entahmeklappe opens automatically. For this price I expect another quality !!!
